摘要：
A viscoplastic model is concerned in this paper, viscosity allows on one hand, to avoid the habitual mesh sensitivity because strain softening is taken into account in the rheological model and on the other hand, to represent the free water effect inside the material which is partly responsible for increasing of strength. Simulation of a dynamic compressive test shows that inertial effect can lead to increase the visible stress. Viscosity and inertial forces as well contribute to delay the damage material.
