摘要
拉-拉应力条件下蠕变疲劳寿命预测,过去,在大多数情况下,采用线性累积损伤法则。然而,本文提出一种新的方法即应变能区分法(SEP)的数值计算方法,计算结果显示出,SEP 的数值法优于文中叙述的其他预测方法。
For creep-fatigue life prediction under condition of the tension-tensile stress inthe past,in the most case,the Linear Cumulative Damage Rule was adopted.However,a new me-thod was advaucecl in this paper,namely,Numerical Computational Appraoch of Strain EnergyPartitioning(SEP).The computing results shown that the numerical computational appraoch ofSEP has prevailed over other prediction method mentioned in the present paper.
