考虑应变率效应的结构响应相似律的研究

Based on the dimensional analysis method, the influence of strain rate effects on the similarity law of structural response under impact load is analyzed. A velocity correction method is provided to decrease the deformation difference due to strain rate effects. The reverse ballistic Taylor impact prototype experiment and model experiment are performed. The velocity correction method is used to guide the reverse ballistic Taylor impact correction model experiment, and the results are compared with the results of prototype experiment and model experiment. The result shows that the velocity correction method can effectively decrease the structure response between prototype and model due to strain rate effects.
