Main project: Deformation and failure of polymeric glasses
Funding: UCL
Supervisor(s): Thomas Pardoen

My research work is focused on the deformation and fracture of (glassy) polymers. Some research topics include:



i) The development of a mesoscale finite element model based on the concept of shear transformation zones (STZs). 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 includes the effect of ageing (and mechanical rejuvenation) and the effect of confinement due to the presence of fibres on the constitutive response of glassy polymers.



ii) Solid-state (nano)foaming of polymers.



iii) Fracture problems in polymers and fibre reinforced polymer composites.
