随著非均匀程度的降低，主破裂呈现脆断模式，而随著非均匀程度的增加而呈现韧性破坏特征。
With the decreasing of heterogeneity , the main failure process presents brittle behavior , and vice versa , with the increasing of heterogeneity , failure process presents ductile behavior.
试验结果表明，该模型机匣的非包容失效模式主要是剪切破坏。
The results indicated that model casing was destroyed by shear stress.
在较高的法向应力下，含起伏角较高齿形节理面的非贯通节理岩体可能出现破坏模式II（先张拉后剪切破坏模式）。
However, at higher angle of tooth-shaped asperities and under higher normal stress, the failure model II is found, which is in first tension but final shear failure.
