摘要/Abstract

摘要： First of all, the concept of γ-p-S_a-S_m-N (confidence level-reliability-stress amplitude-stress mean-fatigue life) surface is presented. Then the formulas of p-S_a-S_m-N surface and γ-p-S_a-S_m-N surface are derived. In addition, fatigue strength distribution function and two-dimensional reliability Miner rule are obtained. At last, an example is given.

关键词: cracked cylinger, Saint-Venant bending, bending center, stress intensity factors, integral equation method, fatigue reliability, p-S_a-S_m-N surface, γ-p-S_a-S_m-N surface, two-dimensional reliability Miner rule
