摘要
水泥砂浆的动态力学行为具有应变率敏感的非线性粘弹特性，并伴随着微损伤的率型演化．给出的水泥砂浆计及损伤演化的率型本构方程，与实验结果吻合良好．
It is shown that the cement mortar(i. e. fine aggregate concrete) has properties of nonlinear viscoelasticity, sensitivity to stain-rates and rate-dependent micro-damage evolution,and the constitutive equation of ZWT can be applied to concrete. A new constitutive relation for cement mortar, a damage-modified nonlinear constitutive equation is presented and verified by experiments.
