摘要
本文讨论了应力和强度均为二维分布时的可靠性模型及可靠度计算,同时导出了在任一应力比下计算相应复合疲劳极限均值及其标准差的公式.
This paper investigates Stress-Strength retiability model of twodimensional distribution and its reliability calculatiou method.The method is based on Monte Carlo Method and Total probabil-ity Formula.It is of high-pricision and easy to use.this papersets forward a series of formulas which are used to calulate meanvalue and standard deviation of composite fatigue limit under anarbitrary stress rate.
