anti-wing crack 反翼裂隙
wing-crack array model 分枝裂纹阵模型
initiation angle of wing crack 翼裂纹起裂角
wing type crack 翼型裂纹
single-wing sliding crack 单翼滑动裂纹
Then the interaction roles between the flaws gradually become stronger and stronger, and principally, the secondary cracks are induced to extend towards the direction opposite to wing crack.
随着各裂纹间相互作用的加强，会引起次生裂纹在预置裂隙端部附近反向扩展的现象，并形成一种新的断裂模式——包裹式反翼裂纹。
The simulations replicate most of the phenomena observed in actual experiments, such as initiation and growth of wing and secondary cracks, crack coalescence, and the macro-failure of the sample.
模拟复制最实际的实验，如启动和增长的机翼和二次裂纹，裂纹贯通，宏观失败的样本中观察到的现象。
