PhD and Post-doc researchers under my supervision:
graduated as a materials science engineer at Université catholique de Louvain (Belgium) in 2013. He is currently doing a PhD thesis (funded by a FRIA grant), started in September 2013 and under the joint supervision of Prof. Thomas Pardoen and Prof. Aude Simar from UCL. His research focuses on the contribution from microstructure heterogeneities on the micromechanisms of ductile damage and cracking in metallic alloys. In order to address these effects on damage accumulation, a combined experimental and a modeling strategy is developed. The experimental strategy relies on in situ tensile testing coupled to 3D microtomography, in situ laminography during sheet loading and a variety of more classical mechanical tests. A cellular automaton type modeling is used to capture particle size distribution and cluster effects on the void nucleation and coalescence processes. His project also involves the use of friction stir processing (FSP) in order to increase the ductility of industrial aluminium alloys of the 6xxx series. From an applicability viewpoint, this method has the potential to locally improve ductility of sheets at locations where forming involves large strains or of structural components at stress concentration points.
|Coupled mechanical-electrical effects in highly strained Ge thin films|
Graduated in chemical and materials science engineering at the Université catholique de Louvain in 2009 (Belgium). Then, under the supervision of Prof. Thomas Pardoen (iMMC) and Prof. Jean-Pierre Raskin (ICTEAM), she accomplished a PhD on the study of the mechanical properties of thin films, more specifically on the plasticity and creep of freestanding nanocrystalline Pd films. The lab-on-chip technique developed previously at the UCL was adapted to deform Pd thin films. After the PhD, she worked for more than two years at the CRM Group in Liège on the development of industrially viable thin film solar cells on steel. From June 2016 to September 2018, she is back at the UCL as a research engineer involved in projects dealing with the understanding of fracture behaviour of high strength steels under a wide range of strain rates. In 2018, she received a 'Chargée de recherches - FNRS grant' and is now working on coupled mechanical-electrical effects in highly strained germanium thin films. Germanium is a promising material for optoelectronic device owing to its compatibility with the standard complementary metal-oxyde-semiconductor (CMOS) technology and to the possibility to convert it into a direct bandgap semiconductor by straining it.
graduated as engineer in chemistry and materials science at Université catholique de Louvain (Belgium) in 2010. In 2015, he obtained at UCL his PhD thesis entitled hierarchical hybrid materials combining wideband electromagnetic absorption and mechanical performance, funded by a FRIA grant. After working one year as a support engineer in the field of extended finite element modeling, he came back at the UCL as a senior researcher involved in applied research projects in collaboration with industry. He is currently dealing with erosion coating on CFRP as well as thermal and electromagnetic management in electrical power converter.
made his PhD on the adhesion of tooth-filling materials to the dentine. He’s now working on composite materials to replace metals in aircraft applications. He takes part to projects studying the mechanical behavior of composite materials (mainly polymer matrix reinforced with long fibers) which are new candidate materials for modern planes. His investigations focus on their bulk, cracking, impact and adhesion properties.
graduated as Civil Engineer at University of Liege in 1992. She began her career with a first experience on the assessment of an existing prestressed railway bridge. Thanks to several FNRS grants, she obtained a PhD degree in the domain of steel-concrete composite structures under seismic action in 2002 and was involved in several researches on paraseismic design at ULg until 2005. After some career break, she joined UCL in December 2008 to take part to the development of new composite activities related to various applied research projects in collaboration with the industry (aeronautics) Her main fields of expertise are the mechanical characterization of composite materials by mechanical testing, the quality control of the standardised tests and the development of new tests. She has also some experience in fatigue testing, damage characterization and fracture mechanics. She is currently working on the preforming of composite thermoset prepreg fabrics.
obtained a PhD degree in the domain of process control in 2009 at Université catholique de Louvain (Belgium), after having graduated there as chemical engineer in 2005. Since then, she is working as a "senior" researcher on several applied research projects in collaboration with the industry in the domain of mechanics of materials. More particularly, she is interested in the link between the mechanical properties of the individual components of a complex system and the global mechanical response of this system. She applied this approach to the framework of tribology and contact mechanics for understanding the scratch resistance of coatings and multilayered systems. Her work covers both experimental aspects and finite element simulations.

Since then he has been a research assistant in iMMC involved in various projects dealing with material science, nanomechanical testing and tribology.
|Influence of defects on the life of biomedical implants|
Implants are devices aiming to support, help, or even correct biological structures. However, with time, some of these implants show aging problems. The roots of these problems can have numerous explanations. In some cases, the body reacts to the presence of a foreign body, and this can lead to health risks. Sometimes, the material can show, with time, signs of weakness. Later on, these defects can lead to the failure of the implant.
In the case of permanent stent implants, the presence of a foreign body in the blood vessels can lead to restenosis or late thrombosis. This is why bioresorbable stents are nowadays developed. These stents should support the vessels during their healing period and dissolve in an inoffensive way afterward. Iron-based alloys are investigated for their appropriate mechanical properties but their degradation rate is too low. One investigated solution is to increase surface roughness to dissolve faster the implant. The effect of this roughness on the expansion process has not been analyzed for now.
The case of growth rods shows that the material itself can lead to implant failure. These rods are placed, during surgery, along the spine of scoliotic children. They aim to support the spine and help it to straighten back. However, fracture events occur in 36% of the patients. During the surgery, the rods are bent to fit the natural shape of the spine. The tools employed for this process can introduce some indentation marks on the surface of the rods and decrease their fatigue lifetime.
From these case studies, it is observed that the completion of an implant (i.e. stent implantation process) or its lifetime (i.e. growth rod failure) can be affected by its surface state. This research will therefore focus on the imperfection sensitiveness of such devices. Various kinds of defects are introduced at the sample surface. To understand the influence of these defects on the mechanical properties, these samples are tested and compared.
|Fracture toughness of high entropy alloys|
High entropy alloys (HEAs) are a new family of metallic alloys. In contrast to conventional alloys, HEAs have multiple principal elements e.g. the equiatomic "Cantor" alloy CrMnFeCoNi. Alloys in this range of chemical composition have gathered attention only recently. From what was observed in conventional alloys, it was expected that HEAs microstructure be composed of several intermetallic phases but some systems are surprisingly single phase solid solution. Moreover, such single-phase alloys have excellent mechanical properties. For instance, CrMnFeCoNi possess a large fracture toughness, which increases with decreasing temperature, putting this alloy on par with the current best alloys used for cryogenic applications. As such, the objective of the thesis is to understand the underlying mechanisms responsible for the observed macroscopic behavior of such alloys.
The thesis aims to answer several questions such as: What are the mechanisms responsible for the increase in ductility, strength, and fracture toughness with decreasing temperature? What high-throughput methodology would be able to screen the vast range of possible chemical composition of HEAs for high performance alloys?
To understand the deformation mechanisms, several HEAs will be fully characterized from casting to mechanical testing. For the fracture toughness measurements, the essential work of fracture method will be employed as it is best suited for ductile thin sheets than compact tests. Diffusion multiples will be explored as a possible high-throughput method, as the presence of composition gradients allows the simultaneous characterization of a range of composition by techniques such as EDX, EBSD and nano-indentation.
|On a chip fracture mechanics test method|
The aim of this research is to develop a new testing method based on an-on-chip concept to measure the fracture toughness of freestanding submicron films. This device consists of two major components, a notched specimen and two actuators. When the test structure is released by etching the sacrificial layer, the two actuators contract, this in turn loads the specimen in traction. In order to define the stress intensity factor expression, which is given by this new model, analytical analysis and finite element simulations must be performed in addition to the experimental part, which is based on the microfabrication techniques. Silicon nitride, silicon oxide and metallic glass thin films will be studied during this work. The major goal of this model is to extract fracture toughness of 2D materials like graphene.
|Electromechanical properties of thin films|
The production of Graphene/h-BN heterostructures and the investiong of their microelectromechanical properties, the production of origami and kirigami stacks of Graphene and h-BN, the raman spectroscopy, SEM, TEM AFM and nanoindentation will be used
|Improving the properties of glass fiber reinforced acrylic thermoplastic resin based composites|
For the manufacturing of continuous fiber reinforced thermoplastic composites (CFRTP), certain monomers can be infused through glass fabric and then polymerized in situ, in order to make a thermoplastic composite part. However, defects - e.g. porosity - can occur in the material, due to the thickness of the laminates and the shrinkage of the resin matrix during polymerization. Such phenomena must be understood, as well as their effects on the mechanical properties of the final composite part.
The originality of this work lies in the very nature of the polymeric matrix used for manufacturing the composite parts, which is thermoplastic instead of thermoset. Little is known about the behaviour of such thermoplastic composites, especially at a microscopic scale. During this PhD, we will try to understand how defects occurring in the material can influence the structural properties of the CFRTP, and we will try to mitigate (or at least control) the incidence of such defects. This will imply a better knowledge of how usual characterisation techniques can be applied from thin to thick composite parts. In particular, digital simulation will be used so as to predict the properties of thick composite parts from those of thinner samples.
|Experimental and numerical investigations on the miniaturization for fracture toughness characterization of RPV materials|
This project deals with the miniaturization of fracture toughness specimen for the characterization of the cracking resistance RPV materials. Indeed, in the nuclear field, the use of mechanics tests to measure fracture toughness of react pressure vessel (RPV) materials, is key for producing reliable integrity assessments and accurate residual life predictions. However, the space available inside irradiation facilities is extreme. Furthermore, the use of normal size specimens leads to significant of radioctive wastes. Miniature Compact Tension specimen, MC(T), as one of the geometries that offers significant advantages, can optimize the use of available material and generate meaningful fracture toughness values. But these specimens still do not comply with existing requirements due to (i) effect of geometry, (ii) effect of side grooving, (iii) effect of loss of constraint, etc. Therefore, in his research project, detailed numerical analysis combined with miniaturization tests are used. The final aim is to better qualify and validate the use of mini-CT geometry in both brittle and ductile fracture regimes.
|Deformation and failure of polymeric and metallic glasses|
Frederik Van Loock
My research work is focused on the deformation and fracture of (glassy) polymeric materials and polymer-based hybrid material concepts such as polymeric foams, adhesive joints, and fibre-reinforced polymer composites. Some current research topics include:
i) The development of a mesoscale constitutive finite element model based on the concept of shear transformation zones (STZs) for glassy materials (polymers and metals). The STZ model allows to predict the complex large deformation response of glassy polymers, including post-yield softening and non-linear unloading behaviour, by calibration of a few parameters via experiments on the polymer of interest. The model also sheds light on the interactions between discrete and elementary distortion mechanisms (and their collective organisation) during plastic deformation of polymeric glasses. Ongoing research with the STZ model includes ageing (and mechanical rejuvenation) of polymers, viscoelastic effects, and the effect of confinement due to the presence of fibres on the constitutive response of glassy polymers. The STZ modelling approach is also being used to study deformation and fracture of confined layers of metallic glasses.
ii) Fracture problems in polymers and fibre-reinforced polymer composites.
iii) The development of a thermochemical model for the in-situ polymerization of a thermoplastic matrix in a fibre-reinforced polymer composite (PhD work of Sarah Gayot).
iii) Fracture problems in solder joints subjected to thermal cycling (PhD work of Vincent Voet).
|Vieillissement thermomécanique des brasures d'assemblage de composants électroniques pour applications spatiales|
Les développements d’électroniques pour applications spatiales nécessitent de garantir une durée de vie de 15 ans avec une probabilité d’échec très faible. L’objet de la recherche sera d’établir des outils de conception permettant l’analyse préalable du comportement en fatigue de ces équipements électroniques. La fatigue des circuits électroniques est dominée par la rupture des brasures des composants montés sur circuits imprimés. Une fois solidaires du circuit imprimé, les brasures subissent tout au long de leur vie des contraintes thermomécaniques liées entre autres à l’inhomogénéité des différents coefficients de dilatation thermique des matériaux qui constituent le montage. Chaque composant combiné à chaque type de report doit donc être caractérisé en vieillissement. Cette caractérisation consiste à réaliser des centaines de cycles thermiques en étuve. Ces essais de vieillissement accélérés prennent plusieurs mois et sont coûteux d’où le besoin de pouvoir estimer les probabilités d’échec ou de succès de façon anticipée.
Cette évaluation permettra de donner un intervalle de confiance sur le succès ou l’échec de la qualification d’un nouveau report de composant ou de l’extrapolation d’un report qualifié dans un environnement étendu. La construction de ces outils sera basée sur de la caractérisation par plans d’expériences physiques ou virtuels et de l’analyse de données relatives aux essais déjà réalisés dans le passé par Thalès Alenia Space.
L’analyse des mécanismes et conditions de fissuration impliquera notamment: Métallurgie des brasures SnPb en lien avec les paramètres de fabrication; Identification de lois de comportement thermoviscoplastiques des brasures SnPb à l’aide de la nanoindentation instrumentée; Calcul, par méthodes numériques, des champs de contraintes dans les composants et les brasures, provoqués par l’inhomogénéité des coefficients de dilatation thermique des constituants sur base du modèle constitutif choisi, de la géométrie locale de la soudure et des paramètres identifiés ;Identification des mécanismes de propagation de fissures et identification des liens avec la géométrie et la métallurgie ; en particulier, un élément clé est de pouvoir déterminer la part prise par la phase d’initiation versus propagation des fissures, dans le but éventuel de justifier qu’une des deux puisse être négligée. Dans ce cadre, il est prévu de générer des soudures avec des défauts artificiels contrôlés afin de voir leur impact sur le processus d’initiation de la fissuration, et de le quantifier. L’utilisation de la microtomographie exploitant aussi la corrélation d’image volumique sera un élément important à ce niveau; Vieillissement des brasures sur base des lois de vieillissement établies ; Quantification des incertitudes par approche statistique et probabilité à partir des données expérimentales et également par variation des paramètres clés dans leur plage d’incertitude (défauts géométriques, variations des paramètres constitutifs, présence des pré-défauts, variations de T° extrêmes, etc); Estimation d’un intervalle de confiance préalable de succès ou d’échec des essais envisagés.
|Corrosion study of the BR1 fuel in highly alkaline conditions|
Natural unalloyed metallic uranium, coated with an AlSi bonding layer and an U(Al,Si)3 anti-diffusion layer, and encapsulated ultimately in an aluminum container, is used as nuclear fuel of Belgian Reactor 1. One feasible solution for the long-term management of these fuels, which will eventually become waste, is the geological disposal in which a direct embedding of these spent fuels in a cement-based material could be used. The main goal of my PhD thesis is to investigate the corrosion behavior of BR1 fuel in a cement-based material. The influences of different cement types (Ordinary Portland Cement, Magnesium Phosphate Cement, etc.) on the corrosion process are compared. The roles of cement porosity in the corrosion process is evaluated and the corrosion inhibition ability of additives such as lithium nitrate and Blast Furnace Slag (BFS) is examined. In this research, Gas Chromatography (GC) and electrochemical techniques involving Electrochemical Impedance Spectroscopy (EIS), Linear Polarization Resistance (LPR) are applied to monitor the corrosion rate. Electron microscopes (TEM, SEM) and X-ray diffraction (XRD) are used to analyze the corrosion products. Micromechanical techniques will be used to evaluate the local mechanical properties of the corrosion products and determine the resistance to cracking. Furthermore, other methods such as corrosion stimulation and more characterization techniques e.g. XPS, FTIR could be utilized if necessary.
|Micro- and nano- mechanical characterisation and modelling of composites at the local fibre/matrix level|
The use of fibre reinforced polymer composites in lightweight structural applications requires the accurate prediction of their deformation and failure mechanisms. Increasing the predictive capabilities of current computational models (mostly phenomenological) implies moving towards multi-scale micromechanics-based approaches. One of the main current bottlenecks in the field is the absence of a sufficiently quantitative micro-scale description of the mechanical behaviour of the matrix, interface and interphase with the fibres. This involves characterising and modelling the origin of the difference of behaviour between the matrix when confined in small volumes between fibres, and the bulk. The development of a proper description of the behaviour of the matrix/fibre interphase and interface regions is another important challenge as they affect the load transfer and failure mechanisms. A key aspect is a proper treatment of the local viscoplastic, back-stress and anisotropy effects within the constitutive framework. The aim of the PhD thesis is to tackle these questions using a combined experimental and numerical approach with application to a thermoset, a thermoplastic and a bio-sourced matrix. Nano/micro-mechanical measurements such as nanoindentation, atomic force microscopy and in-situ testing within a scanning electron microscope relying on micro-digital image correlation, will be conducted to evaluate the matrix and interphase responses as a function of strain rate and degrees of cure. Push-out tests will be used to characterise the interface behaviour. The outcome of these tests will be used to enrich molecular-informed micro/meso-mechanical models. The success of the research project will be measured, at the fundamental level, by the capacity to unravel the size and molecular-structure dependent deformation nano/micro-mechanisms, and, at a more applied level, by the ability to model the macroscopic response of UD composites based on the constituent properties.
|Though hybrid nanolaminates|
I am particularly interested in the mechanical characterization of the multi layered materials and their deformation mechanisms. I use nanoindentation and lab-on-chip techniques together with TEM observations of the deformed nanolaminates to enhance the understanding of their surprising mechanical behavior.
|Assessment of mechanical properties of fusion materials by micro-mechanical testing|
My Ph.D. project is about the assessment of mechanical properties of fusion materials by micro-mechanical testing. Miniaturization of test samples is required for limiting the amount of activated materials and to allow homogeneous irradiation. It needs to be correlated with standardized test methods. This involves fracture toughness tests with miniaturized three-point bending samples or miniaturized disc-shape compact tension test samples.
And as the plasma-facing component, the materials will face severe irradiation conditions and it is thus important to demonstrate the tolerance of mechanical properties to neutron irradiation to satisfy acceptable safety limits. There are mainly three types of materials addressed in this thesis, tungsten, RAFM steel, and CuCrZr. Tungsten is a promising material for divertors that need to resist high heat flux. RAFM steel is used for structural applications. It also an appropriate material to assess the method for the determination of the DBTT (Ductile Brittle Temperature Transition) and to correlate to tungsten. Both materials are BCC structure, but steel is cheaper and easier to perform experiments in order to build a reference database. CuCrZr is used as heat sink materials.
|Development of a sustainable building composite material with high reuse or recycling potential|
The construction sector is one of the most energy consuming in terms of resource and energy, waste production and greenhouse gas emissions. In this field, the waste recycling rate is low and leads to severe environmental impacts, in addition to those caused by the production of materials. New construction technologies are constantly developing, encouraged by the EU and Belgium, such as (i) eco-construction, which is more sustainable and responsible, (ii) new materials derived from bio-based raw materials with less energy-consuming production, and (iii) the integration of the concept of circularity by extending the life cycle of materials to multiple uses rather than just on and using waste in new production cycles.
The project fits into this context to respond to current ecological challenges by developing new circular and sustainable building materials. Research will focus on composite materials made, especially, from recycled fibers. The approach will combine a rational material selection procedure, processing, characterization of microstructures, evaluation of properties and modeling, with the target to reach enhanced environmental performance indices under architectural constraints. The relationship between composition, structure and properties of these new materials involves many scientific questions. A preliminary master thesis work has already shown the energy-efficient nature of the manufacture of these materials and their excellent potential in terms of insulation, fire resistance and mechanical resistance for materials which contain a proportion of paper fibers greater than 50%, it’s a majority of recycled materials in its composition.
|New extrinsic toughening solutions for composite/metal joints: processing, characterization, testing and modelling|
Charline van Innis
In aerospace, several structural components combine composite and metallic parts that must be joined together. Adhesive bonding is an attractive solution that avoids stress concentrations such as caused by mechanical fasteners while the bonding step can be integrated in the manufacturing process. One remnant problem is the lower fracture resistance of the joint compared to the adherents. The objective of the thesis is to improve the joint integrity by investigating extrinsic toughening mechanisms. Three mechanisms are proposed. For the first one, the architecture of the joint will be modified by inserting holes or a pattern on the metal adherent to stop or deflect the crack. The second will be based on co-cured TP/TS interfaces allowing crack trapping in a tough zone. For the last one, an additional layer will be added near the joint in order to increase the energy dissipation during crack propagation. The effect of each one on joint toughness improvement will be investigated. Each can be used alone, but their combination will also be investigated. The proposed approach is based on experimentation and simulation. First, the materials must be selected before manufacturing the joints via the different techniques. Then, mechanical characterization will allow to assess the impact of the chosen mechanism on the joint toughness. In order to understand the failure mechanisms taking place, morphological and chemical characterization will be needed, but also nanoindentation to determine the local properties. Finally, multiscale modelling of the joint will allow, once the model will have been validated, to optimize the joint and to investigate the combination of the three mechanisms mentioned previously.
|Analysis and understanding of the damage and fracture mechanisms in advanced high strength steels for automotive applications|
The environmental challenge the world is facing today is driving car manufacturers to limit their vehicule weight in order to reduce their fuel consumption. As a consequence, steels with higher specific strength performances are being constantly developed, while insuring that proper ductility and toughness levels are retained to allow for forming operations and passengers safety. Lately, the so-called "third generation" of advanced high strength steels (AHSS) has emerged, among which one finds the Quenching & Partioning (Q&P) steels. These Q&P steels demonstrate an excellent combination of ultimate tensile strength (UTS = 1500 MPa) and adequate ductility (TE = 18%). Nevertheless, their fracture properties and the underlying mechanisms are still not fully understood and start raising concerns as the strength levels of these steels increase. Indeed, recent studies have highlighted a shift in failure mechanism, from ductile to brittle, depending on the loading conditions. Although often left behind strength and elongation, toughness issues constitute essential stakes not only for ever more demanding applications but also for forming processes during which edge cracking is a key concern. The objective of my research project is to investigate the failure properties of these Q&P steels in order to understand how microstructural and micromechanical parameters influence the competition between three possible mechanisms : ductile flat, ductile slant and brittle intergranular.
