Technical Field

Background
The fatigue endurance test of the parts detects the fatigue characteristics, the fatigue life, the pre-crack and the crack propagation test of the metal, the alloy material and the components (such as an operating joint, a fixed component, a spiral moving component and the like) thereof under the condition of tensile, compression or tensile-compression alternating load at room temperature. Under the action of large enough alternating stress, the metal member may have abrupt change in shape, surface indentation, internal defect, etc. and may have micro-cracks caused by large stress concentration. The dispersed microcracks will form macrocracks through aggregate communication. The macrocracks that have formed gradually and slowly propagate and the cross section of the component gradually weakens, and when a certain limit is reached, the component suddenly breaks. The above-mentioned failure phenomenon of metals due to alternating stress is called fatigue of metals. Statistics show that failure of mechanical parts, about 70% or so, is caused by fatigue, and that the majority of accidents caused are catastrophic.
