摘要
从能量耗散的角度,提出了一种由高斯积分算法计算损伤的混凝土单轴受拉损伤模型,推导了损伤变量D的方程式,通过与几种典型的单轴受拉损伤模型进行了比较,初步验证了本文模型,表明本模型形式简单、精确度高、工程应用方便。
From the aspect of the energy dissipation,the paper points out the damage model of the concrete uniaxial compression calculated by Gauss integral calculation,induces D equation of the damage variable,and compares some typical uniaxial compression model,proves the model in the paper,and reflects the model is simple in the form,high in accuracy and convenient for engineering application.
