【摘要】 本文较为详细地综述了预测疲劳裂纹形成寿命的局部应力应变法，分析评论了各种算法的优劣，分析了三个试验和计算的结果，结果表明，瞬态应力-应变曲线和等效应变-寿命曲线的组合算法精度最好。更多还原

【Abstract】 A brief review of local stress-strain approach for predicting fatigue crack initiation life is presented. A simple comparision among all kinds of methods is made. Three experemental and numerical results show that instantaneous σ~εcurve+εeq~Nf curve is the most accurate for the prediction of fatigue crack initiation life.更多还原
