Considering the requirement of a precise stress-strain relationship, a new constitutivemode-the elastoplastic anisotropic damage model of the constructional metal is put forward,which includes the mixed hardening criterion, Bauschinger effect, yield plateau, hardening(softening)influence, damage and damage evolution.
结构钢本构关系的精度直接影响分析结果的可靠度。 本文采用混合强化准则，考虑Baushinger 效应、屈服平台、硬化（软化）效应、损伤和损伤演化的影响，首次建立了结构钢弹塑性各向异性损伤本构模型，为实现精确数值分析奠定了基础。
