中文摘要
在宏观弹性应力状态下,测量了不同循环加载条件下的塑性变形。提出了弹塑性本构模型来再现实测的应力-应变关系。基于循环塑性模型预测的累积塑性功,提出了疲劳裂纹萌生判据的原型模型。
英文摘要
The plastic deformation was measured during various cyclic loading conditions under macroscopically elastic stress state. The elasto-plastic constitutive model was proposed to reproduce the measured stress-strain relationships. The prototype model for the fatigue crack initiation criteria was proposed based on the accumulated plastic work predicted by the proposed cyclic plasticity model.
