摘要
研究了疲劳损伤的合理定义,给出了适当的损伤累积法则应当满足的必要条件,建立了一种以有效循环塑性应变能耗为基础的疲劳损伤非线性累积法则。并从理论和实验两方面证明了该法则能够正确反映载荷次序效应等疲劳累积损伤规律。
The reasonable definition of fatigue damage have been studied, the condition that need be meet to a useable cumulative damage rule was provided, and a practical fatigue cumulative damage rule, which uses the effective cyclic plastic strain energy dissipation as damage internal variable, was suggested. The present cumulative damage rule is able to correctly describe the loading order effect, about which a rigorous theoretical and experimental proofs was provided in this paper.
