fatigue fracture造句

The fatigue fracture characteristics were fatigue striation, ductile microvoid, and quasi-cleavage-like fracture characteristic.

The failure of most valve springs is due to the applied positive stress resulting in the fatigue fracture.

The correlative nature is revealed between the morphology and orientation of the striations on fatigue fracture surfaces.

The stress whitening can be clearly seen on the fatigue fracture surface and its region is the initiation and nucleation of fatigue crack which is the main part of total fatigue life.

The results showed that manufacturing defects of the bolt resulted in initiation and propagation of fatigue crack, and uneven loading of the bolt speeded up failure process of fatigue fracture.

The main reason for the fatigue fracture of material is that the specimens under action of alternating stress engender slip, finally resulting in dislocation stacking.

Under the action of tensile stress and tensile stress, the bolt with relatively low strength will crack first, and then the fatigue fracture will occur.

Fibrillation cleavages were observed on torsional fatigue fracture ends of para-aromatic fiber while creep characteristics was observed on the skin of UHMWPE fiber and the brittle rupture in the core.
