...-volume relationship includes permanent densification and bulking. Damage is accumulated based on plastic strain, pressure and strain rate. Simple (single-element) examples are presented to illustrate the capabilities of the model. Computed results for more complex ballistic impact configurations are also...

... lateral shape. The experimental results are used along with several assumptions to extract a more representative stress-strain response of foam. The response is characterized by the initial plateau stress, shape exponent and densification strain. The significant effect of the variable Poisson’s ratio...
