• 1. crack branching: 裂纹分叉 | 裂隙分支
• 2. branching crack: 枝状裂纹
• 3. inclusion-branching crack: 夹杂分枝裂纹

• 1.Their toughening mechanisms were fine-grain toughening, crack deflection, crack branching and crack microbridging.
  韧化机制为细晶韧化、裂纹偏转、裂纹分支和微桥接。

• 2.Consequently, at the macroscopic crack branching velocity, the experimental fracture surface energy and the fracture surface roughness; have no single value in such materials.
  因此，对这种材料在宏观裂纹分叉速度时，实验断裂表面能及断裂表面韧性没有单一值。
