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

对软弱面力学失稳产生机理的澄清和定量评价的理论研究得到了进一步扩展。结合实验力学技术，讨论了与软弱面机械失稳有关的物理现象的产生机制和失稳诱发波的特征。已有研究表明，如果我们把一组受动力冲击的结构的力学行为看作一个“组”(即不是针对每个结构单独处理)，我们可能会系统地解释一种无法通过传统分析预期的未知的力学行为。

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.
