A proper numerical simulation method is developed to simulate the structure impact problems that consider the effect of strain rate. The high-speed tensile tests are carried out to obtain the strain-stress relations of different strain rates, and used as material inputs to analyze the dynamic response of laterally impacted stiffened plates. The simulation results are compared with falling weight impact experiment, and good agreements are obtained. The strain-stress relations obtained from high-speed tensile tests and Cowper-Symonds constitutive (CS) model are compared. It shows that curves gotten from CS model are higher than those gotten from high-speed tensile test; with the strain rate increasing the distance will became obverse, and the validation of the numerical simulation is verified and can fit the experiment result very well.
