If the plastoelastic fatigue notch factor was regarded as the transforming factor of damage calculation, the data scattering zone of life curve was most narrow.
采用此方法确定疲劳缺口系数，获得的损伤参量与裂纹形成寿命关系的数据分散带最窄。
The development of the models of the elastic , plastoelastic , cracking , failing , thermal expanding and manufacture technology in metal matrix composites is reviewed.
