摘要: 以连续损伤力学(CDM)为基础，根据Ti-6Al-4V钛合金应变疲劳试验结果，改进了Krajcinovic和Lemaitre提出的损伤本构模型，并拟合确定了损伤模型参数；将该损伤本构模型编写为USDFLD子程序并耦合到ABAQUS有限元软件中. 使用Chaboche非线性随动强化和非线性各向同性硬化的混合硬化模型来描述Ti-6Al-4V钛合金的弹塑性行为，并拟合确定了混合硬化模型参数. 模拟了材料在不同应变幅下的低周疲劳损伤演化. 结果表明，损伤模型预测寿命和试验寿命吻合较好，对比试验和模拟结果可以发现，损伤模型预测寿命的平均误差为3.878%.Abstract: The damage constitutive model proposed by Krajcinovic and Lemaitre was improved according to the result of the strain fatigue tests of Ti-6Al-4V titanium alloy based on the continuum damage mechanics (CMD), then parameters of the damage model were determined through fitting the strain fatigue data. The damage model was compiled into USDFLD subroutine, then this USDFLD subroutine was coupled into ABAQUS software. The combined hardening model mixed with Chaboche nonlinear kinematic hardening and nonlinear isotropic hardening was used to describe the elastic and plastic behavior, the parameters of the combined hardening model were determined through fitting the strain fatigue data. The fatigue damage evolutions of the material under different strain amplitude were simulated. The experiment results showed that the prediction life based on the damage model was in good agreement with the experimental life. Comparing the results of experiments and simulations, the average error was 3.878%.
