摘要
利用概率论方法建立了应变疲劳强度概率分布与应变疲劳寿命概率分布之间的数学关系式，并根据应变——寿命转换关系，由已知的给定应变水平下的疲劳寿命概率分布求出给定寿命下的应变疲劳强度分布函数，便于进行可靠性分析。关键词：应变疲劳；应变强度；
In this paper, the mathematical relation between strain fatigue strength distribution and fatigue life distribution is theoretically established by probabilistic approach. Accorcling to inverting relation ship between strain and life, probabilistic density function of strain fatigue strength at a prescribed life is derived from that of fatigue life at a given strain level. The theoretical basis for strain fatigue reliability analysis and assesment is provided.
