摘要:基于连续损伤力学和塑性力学理论形成的弹塑性损伤帽盖模型是一个高级混凝土本构关系模型，但模型涉及的参数过多却给运用造成了不便。本文对模型参数进行详细解释基础上，采用已有的混凝土材料试验数据给出了其子午线强度参数、帽盖参数、脆性损伤和延性损伤参数取值，大大方便了工程运用。最后以单轴拉伸和单轴压缩为例数值演示了模型基本力学特性。

Abstract: Elasto-plastic damage cap model is an advanced constitutive model for concrete, based on continuum damage mechanics in combination with plasticity theory. However, too many parameters involved in this model bring inconvenience in the course of application. Detail explanations for its parameters are made first, parameters for meridians, cap surface, brittle damage and ductile damage of the model are given according to test data for concrete materials, which ease its engineering application greatly. At last, basic characteristics of the model are demonstrated through the uniaxial tensile and uniaxial compressive simulation.
