List of projects related to: granular materials
Researcher: Nicolas Docquier
Supervisor(s): Paul Fisette
The project aims at improving railway track lifecycle by improving its components such as the ballast, the sleeper, elastic pads, ... It consists in developing computer models coupling multi-body system dynamics (MBS) and granular modelling method (the discrete element method, DEM). Full scale experiments are conducted in parallel to validate the numerical models and assess the developed solutions.
|Crane dynamis (CRAMIC)|
Researcher: Olivier Lantsoght
Supervisor(s): Paul Fisette
Historically, the cranes of the ports were assumed to be static or cyclical but, because of the increases in speed and loads, they are becoming more and more dynamic. As a result, load on the rail tracks is increasing and negative effects occurs (such as uncontrolled motion, track deformation…). As one of the partners of CRAMIC global project, through multibody and granular analysis of the system crane-railway.
On one side, we focus on identifying and studying the present dynamic effects, participating in developing new track technologies and helping monitoring cranes to organize a future maintenance. On the other side, we focus on the interaction between sleepers and ballast, participating in creating new sleeper geometries.
|Modèle hybride multi- échelle pour l’ étude rh éologique des solutions de macromolécules|
Researcher: Nathan Coppin
Supervisor(s): Vincent Legat
graduated in physical engineering at Université Catholique de Louvain in 2018 and is currently pursuing a PhD under the supervision of Prof. Vincent Legat. The goal of his thesis is to study the performance of the MigFlow Software using applications that require the management of frictional contacts.
|Numerical Modeling and Simulation of Sediment Mobilisation and Transport due to Turbulent Currents|
Researcher: Anouk Riffard
Supervisor(s): Miltiadis Papalexandris
The proposed doctoral research evolves around two principal axes. The first one is the development of mathematical models and algorithms for flows of fluid-solid particles mixtures, i.e. granular suspensions. The second one is the use of these algorithms for the study of sediment mobilisation and transport due to turbulent currents.
|A phase-field discrete elements model applied to granular material|
Researcher: Alexandre Sac-Morane
Supervisor(s): Hadrien Rattez
The main goal of the research project is to combine a phase-field modelization with a discrete elements modelization. This new approach is then applied to granular material to investigate the effects of the environment. A model is built and will be calibrated by experiments.
