Modeling large deformation and failure of expanded polystyrene crushable foam using LS-DYNA

In the initial phase of the research work quasi-static compression tests were conducted on the expanded polystyrene (EPS) crushable foam for material characterisation at low strain rates (8.3x10-3~8.3x10-2 s-1) to obtain the stress strain curves. The resulting stress strain curves compared well with...
