摘要
该文对大型非线性有限元分析软件ABAQUS中的混凝土塑性损伤模型进行了详细的介绍。着重讨论了混凝土塑性损伤模型的基本理论和损伤因子基于《混凝土结构设计规范》(GB50010-2010)[4]附录C应力-应变曲线的计算方法。同时也对ABAQUS中塑性损伤材料模型的滞回规则、屈服准则和流动法则作了简要介绍。
Concrete plastic damage model in nonlinear finite element analysis software ABAQUS is introduced in detail. The basic theories of concrete plastic damage model and the calculation methods of the damage factors based on stress-strain curve in appendix C of Code for Concrete Structures De-sign （GB50010-2010） [4]are discussed in particular. Also, the hysteresis rules,yield criterion and flow rule for plastic damage material model in ABAQUS are introduced for reference.
