摘要 | This paper studied the microstructure sensitivity to very-high-cycle fatigue of metallic materials based on Tanaka and Mura model by using Monte-Carlo method. In this simulation, local stress, frictional stress and inclusion size are assumed to be random variables, and two sensitivity indicators are proposed: sensitivity of mean value and sensitivity of standard deviation. Results indicate that fatigue failure is most sensitive to frictional stress, and the dispersity of variables also influences the fatigue life |
