摘要

基于ZWT粘弹性本构模型和服从威布尔分布的材料损伤演化，提出了损伤热粘弹性本构方程。该模型应用于混凝土和水泥砂浆材料。通过数值拟合，得到了本构模型的参数。模型预测结果与实验结果的比较表明，两者吻合较好。

High temperature dynamic constitutive relation of concrete-like brittle material

Based on ZWT visco-elastic constitutive model and damage evolution of material submitting Weibull distribution, a damage thermo-visco-elastic constitutive equation is proposed. The model is applied by concrete and cement mortar material. Through the numerical fitting, the parameters of the constitutive model are obtained. A comparison between model prediction and experimental results shows that both of them are agree well with each other.
