The investigation shows that the vertical shaft of the front fork is subject to fatigue flaw due to the cyclic stress, which leads to the fracture of the vertical shaft.
The effects of quenched-in crystallites on the cyclic fatigue fracture of Zr-Al-Ni-Cu bulk amorphous alloy were investigated.

Moreover, the irreversible plastic deformation of rock increased, and at the same time, the fracture deformation of rock gradually increased, which was produced by cyclic load.
