In the crack propagation process, grains near the main crack are deformed and elongated tempestuously, resulting in their breaking and new grains with high angle grain boundary formed.

在裂纹扩展过程中，强烈的内应力使主裂纹附近的晶粒产生剧烈的变形，拉长直至破裂，并形成新晶粒；新形成的晶界表现为大角晶界。

The tensile stress at the crack tip is the driving force for the crack propagation.

The direction of crack propagation is victual to the direction of maximum stress if the anisotropy of material is sufficiently weak. Universality of fractal dimension of fractured surface would be easy to appear in this case. On the contrary, the crack propagates along the plane with the lowest surface energy.

当材料结构的各向异性特别显著时，裂纹的扩展沿着比表面能最小的方向扩展，这时，断口分维与材料本身的结构有关，表现为断口分维的特殊性；反之，当材料结构的各向异性特别微弱时，裂纹的扩展垂直于最大应力方向，在这种情况下，材料的断口分维与普适性有关。
