The theoretical study for clarification and quantitative evaluation of the generation mechanism of the mechanical destabilization of planes of weakness has been further extended. Together with the techniques of experimental mechanics, the generation mechanisms of physical phenomena related to the mechanical destabilization of planes of weakness and the characteristics of the destabilization-induced waves have been considered. It has been shown that if we treat the mechanical behavior of a group of structures subjected to dynamic impact as a “group” (i.e., not individually for each structure), we may systematically explain an unrecognized mechanical behavior that cannot be expected through conventional analyses.

进一步拓展了弱面力学失稳产生机理的理论研究和定量评价。结合实验力学的方法，研究了弱面力学失稳的物理现象的产生机理和失稳诱发波的特征。已经表明，如果我们将受到动态冲击的一组结构的力学行为视为“组”（即，不是针对每个结构单独地），我们可以系统地解释无法通过常规分析预期的未识别的机械行为。
