摘要：
Discontinuities of microstructure in steels induce stress concentrations. Microplasticity is the plasticity which exists locally in the locations of these stress concentrations, whereas the remainder of the material is in the elastic range. The initiation of fatigue cracks thus takes place in the areas where there is some microplasticity. The microplasticity threshold is the nominal stress in uniaxial symmetric loading from which microplasticity exists.
