摘要
从概率疲劳和概率断裂力学角度出发，以结构细节疲劳特征强度为基础表示结构的疲劳特性，给出了结构细节疲劳特征强度随裂纹长度变化的数学表达式，对整个ＳＮ曲线的特征作了更深入的探讨。
A durability analysis method from probabilistic fatigue and probabilistic fracture mechanics is described,in wich the fatigue characteristic is expressed with structural Detail Fatigue Rating Strength(DFRS).The relationship between DFRS and Crack size a is given,and a deeper research is done on full S-N curves feature.
