以两种不同的等效方法ＲＭＳ和ＲＭＰ计算等效载荷，并用这两种等效载荷研究渐增块载条件下的疲劳寿命，经数值计算表明ＲＭＳ和ＲＭＰ方法的结果是比较接近的，而且也较好地符合了实验结果。作者建议两者都可以用于缺陷评定中变幅载荷下的疲劳寿命计算
The RMS and RMP equivalent loads were calculated by two different equivalent methods, and the fatigue life under increasing bulk load was studied by these two equivalent loads. The numerical results show that the RMS and RMP methods are relatively close, and Also better in line with the experimental results. The authors suggest that both can be used for fatigue life calculation under flanging loads in defect evaluation
