摘要 提出了一种新的损伤塑性本构模型,定义了一个用应力不变量表示的应力三轴比,强调了应力三轴比对塑性屈服的影响。采用本研究设计的专门用于本构校验的计算机软件,对上述模型的应力应变加载曲线进行了数值模拟,数值结果与实验结果吻合得比较好。 A plastic damage constitutive model was proposed with special concerns on simulating the stress-triaxiality-dependent hardening phenomena. The stress triaxiality was defined in terms of stress invariants. A subroutine was developed for validation of the constitutive model at local level. Comparison between the numerical results and experimental data indicates the validity of the proposed model and the related numerical scheme.
