Synthetic Study on the Mechanical Destabilization of Planes ofWeakness, Dynamic Rupture Propagation and Wave Radiation

进一步拓展了阐明和定量评价软弱面力学失稳产生机理的理论研究。结合实验力学技术，研究了与弱面力学失稳有关的物理现象的产生机理和失稳诱发波的特性。研究表明，如果我们将一组结构在动态冲击下的力学行为视为一个“群体”（即，不是每个结构单独），我们就可以系统地解释传统分析无法预料的未被认识的力学行为。

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.
