弹粘塑性本构模型出发，考虑混凝土材料的损伤，推导提出混凝土弹粘塑性损伤本构模型，适用性强大。本模型能够反映出材料不同的拉压性能、材料的应变率敏感性、静水压力及中间主应力的影响，具有一定的实用价值。(Based on the constitutive model of the elastic viscoplastic constitutive model, the damage of concrete materials is considered, and the constitutive model of concrete elastic viscoplastic damage is deduced. This model can reflect the influence of different tension and compression properties, strain rate sensitivity, hydrostatic pressure and the main stress of the material, which has a certain practical value.)
