Abstract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。; Structures will always respond to the action of external loading to some extent. With the gradual increase of the external loads, the structural deformation will be in the elastic range at beginning, and then elastic-plastic deformation will occur if the external loading exceeds the elastic limit loading capacity of the structure [1]. Practical engineering structures are usually made up of many basic structural components such as beams, plates, arches, shells and so on. When these basic structure.
