通过对相似模型中若干力学量和典型动力学实验中部分结果和结论的探讨分析，研究了动态载荷下率相关材料相似模型的尺度效应，阐述了塑性应变率具有的尺度效应对相似模型在动态载荷下的影响，指出了塑性应变率尺度效应的一个重要特征是，随着结构特征尺度的减小，其动力行为的应变率敏感效应增强。

By analyzing some mechanical quantities and typical dynamictesting results for similar models, this paper studies the scale effect pertaining to similar models made of strain-rate dependent materials, and also describes the effect of plastic strain rate on the mechanical behavior of similar models under dynamic loading. It has been pointed out that the strain-rate sensitivity for dynamic behavior increases with the decrease of the characteristic dimension.
