The work included in this poster presents the development and validation of a bicycle helmet finite element model (FEM). Non linear constitutive equations are determined experimentally for the helmet liner (expended polystyrene) and for the shell (polycarbonate). After meshing of the helmet and the Hybrid 2 headform, a surface to surface interface was introduced between both models in order to constitute the global model. The validation procedure under impact environment against a flat and a curved anvil shows reasonable agreement at both head acceleration and post impact helmet deformations levels.
