The sliding crack model has been widely applied in the damage and fracture analysis of the rock-like materials.
滑动裂纹模型被广泛应用于岩石类材料压剪断裂分析及损伤分析。
Compared with the classical sliding crack model,the influences on the SIFs due to the angle of wing crack with respect to the main crack,the length of wing crack and the presence of confining pressure are discussed in detai.
结合经典的滑动裂纹模型 ,讨论了裂纹起裂角、侧压以及翼裂长度等对应力强度因子的影响 。
Compared with the classical sliding crack model,the influences on theSIFs due to the angle of wing crack with respect to the main crack,the length of wing crack and the presence of confining pressure are discussedin detail.
讨论了裂纹起裂角、翼裂长度以及侧压等对应力强度因子的影响,并和经典的滑动裂纹模型的结果相比较。
Considering the complexity the complexity and inhomogeneity of rock, especially the presence of some interfaces of weak strength between mineralgrains,an analysis on the single-wing sliding crack (SWSC),is presented.
针对岩石的复杂性和非均质性,特别是岩石中一些强度相对较弱的晶界的存在等,本文对形状较为复杂的单翼滑动裂纹的应力强度因子进行了分析。
