Geometrical effect, crack path kinking and deflection, particle bridging and crack shielding are the main toughening mechanisms.
层间增韧的几何效应、裂纹传播路径控制、裂尖屏蔽和颗粒桥联是主要的增韧机理。

At last the crack that it has formed in the steel based phase connects back and forth cracks of it by bridging.
最后，在钢基体相中形成的裂纹以“搭桥”方式将其前后的裂纹连接起来。
3
The semi-infinite crack propagating in infinite region with the fiber bridging traction action is equal to the semi-infinite crack propagating in strip.
