摘要
从平均应力和断裂力学的观点评述了残余应力对材料疲劳极限的影响。讨论了在残余压应力场中无限疲劳设计时疲劳极限的确定和有限疲劳设计时疲劳寿命的预测的判据。
Reviews the effecf of remanent stress on fatigue strength by the concept of average stress and fracture mechanics respectively.Defination of fatigue strength in unlimited fatigue design and forecasting judge in limited fatigue design are discussied in remanent stress field.
