High temperature dynamic constitutive relation of concrete-like brittle material

Abstract

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.
