The material used in the calculations is taken to be stainless steel that has substantial strain hardening and moderate strain rate sensitivity [8].
Stress-strain curves are plotted in Fig. 2, the relation between true stress and true strain is taken to be strictly bilinear for each value of plastic strain rate .The relative density of the square honeycomb core, , defined as the ratio of average density of the core to the density of material .
The dynamic responses of the square honeycomb sandwich plates are compared with solid plates of the same material and equal mass per unit area subjected to impulse loads.

Since then, the mechanical response of different materials under different impact velocity begun to attract attention by scholars.
When it comes to simulation on crack proagation of heterogeneous materials, based on theory of meso-linear nature of Weibull distribution and meso-structure linear behavior of materials can reflect the principle of macro-nonlinear behavior, RFPA(The realistic failue process anlysis) has been widely used to investigating the failure process of heterogeneous materials.
