THE RESEARCH ON ACCUMULATIVE DESTRUCTION RATIO METHOD OF FATIGUE LIFE UNDER SPECTRUM LOAD

  • This article presents a new method to es-timate fatigue life under spectrum load, accumula-tive destruction ratio method. According to the con-stant amplitude experimental results, this methodcan obtain the characteristics of paxent materialand estimate the fatigue life under spectrum loadwith accumulative destruction ratio method. Thismethod is easy to use and the result of estimationin some cases is better than that of other methods.
