Research Abstract |
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.
