OSTI ID:3933
We report here on the development of a multi-material hydrocode for simulation of elastoplastic flows with large deformations. Using this hydrocode a new constitutive model for porous elastic-viscoplastic materials has been evaluated and the penetration of an aluminum projectile into porous rock material has been simulated numerically. The dependence of the penetration depth upon model parameters has been studed.
