  • The quasi-static and dynamic compression tests of expanded polystyrene (EPS) foam material were carried out through a universal material tester and a drop-weight impact machine. The density and loading rate effects of the dynamic compression characteristics for the polystyrene foam material were discussed. By considering the density correlation, the empirical formula of dynamic constitutive relation under constant strain rate was modified based on the drop-weight test data. The constitutive model of EPS foam was established based on the material finite element models of MAT57, MAT163 in LS-DYNA, and Low Density Foam and Crushable Foam in ABAQUS. By simulating the impact process of drop-weight and comparing with the test results, it shows that MAT163 and Crushable Foam model can predict the dynamic response and energy absorption performance better. The results verify the reliability of the dynamic constitutive model. Meanwhile, it shows that these two specific material models have good applicability in simulating the impact problem of EPS foam.
