RESEARCH THEMES
Polymer foams, Personal protective equipment (helmets)
RESEARCH ACTIVITY
Recent research has centred on the micromechanics of polymer foams, using Finite Element Analysis to develop micromechanics models of foam mechanical properties, and on the impact performance of helmets for cyclists and motorcyclists.
