摘要
基于晶体塑性滑移理论建立了IC10的本构模型,通过在ABAQUS软件平台上编写用户子程序(UMAT),模拟了IC10合金在600℃下的拉伸应力-应变曲线和不同载荷条件下的拉-压疲劳迟滞回线。通过对比发现模拟所获得的计算曲线与试验曲线具有良好的一致性,表明所建立的模型可以有效预测IC10合金在不同载荷下的高温力学行为。
Constitutive model is established based on the plastic slip crystals theory.By writing UMAT,the stress-strain responses of IC10 alloy under different loading conditions are simulated based on the present model.By comparison,it is found that the calculated curves are well consistent with the experimental results.It indicates that the constitutive model can be used to reasonably describe the high-temperature mechanical behaviors of IC10 alloy.
