摘要：

The model of SMA reinforced composite is separated into three parts: reinforce, interphase and matrix. Taking effect of strain rate into consideration, the visco-hyperelastic model is employed in the constitutive law of interphase part. A damage model based on Hashin criterion is developed to simulate the SMA reinforced composite plate subject to low or high velocity impact. Effect of the impact velocity on the shape memory alloy reinforced composite plate under fixed boundary condition is investigated by finite element method, also as the damage state. Low velocity is applied to the model firstly to illustrate the accuracy of parameters and procedures by comparing with the experimental data. In next step, several impact velocities are applied during the simulation process to invest the impact resistance and failure mechanism. Simulation results indicate that damage model of composite is sensitive to loading speed and it is easier for the creak to grow under high velocity.
