Simulation of an impact test of a composite with closed cell aluminium foam
Original language description
This paper focuses on modeling and simulation of deformation behavior of a sandwich structure composed of closed-cell metal foam, expanded polystyrene and plastic foil. Such a structure is intended to be used for energy absorbing applications such as motorcycle helmets. First, individual materials as well as sandwich panels were tested in a drop tower for different impact velocities to generate high strain rate conditions. The digital image correlation method was employed to use stress-strain curves atthree impact speeds. Second, virtual experiments with selected strain rate sensitive constitutive models were performed to best fit the experimental results. Good correlation between experimental and numerical results was achieved with Chang?s continuummaterial model for low density foams. Parameters of the model were identified directly from the experimental stress-strain curves. Finally, continuum finite element simulations of a sandwich structure were performed and compared with expe
