My Research

Simulation of High Strain Rate Deformation in Structural Polymeric Foams

Sponsored by Jaguar Land Rover

Energy absorbing foams are a critical part of occupant and pedestrian protection systems and are vital to delivering the legal and consumer safety standards demanded by the automotive industry. My research aims to improve the virtual modelling capability for structural polymeric foam, and implement my findings into my sponsor company Jaguar Land Rover.

The material model used within the chosen simulation package needs to accurately model the mechanical performance of the material. In order to do this my project has been split into both characterisation of the polymeric foams and FEA correlation within LS-DYNA.

Currently I am investigating Expanded Polypropylene, a structural foam used within the headrest and surrounding trim. Using computed tomography, I have scanned the foam and reconstructed it in meshing software. The block has then been compressed within LS-DYNA and compared to the characteristics of the original material. Accurately modelling the foam will help when characterising new and innovative material in the future.
