felicity ratio 中文意思是什麼
felicity ratio
解釋
費利西蒂比-
It is found that cyclic loading at high differential stress level will lead to the decrease of felicity ratio, and the value max can be decreased by some crack systems in specimen. there is still a lot of ae during unloading at high differential stress level, which implies that the deformation is dominated by fracturing at low differential stress level, and the deformation by frictional sliding increases greatly at high differential stress level
關于應力方式對巖石破裂的影響，發現較高差應力水平下的多次循環加卸載會使felicity比減小；某些構造能使巖石產生felicity效應的應力門檻值_ （ max ）降低；由高差應力水平下卸載時仍有大量聲發射產生推測：在低差應力水平下，破裂以裂紋尖端的突然擴展為主；在高差應力水平下，沿已有的裂紋面的滑動破裂大量增加。
