水泥砂浆的率型损伤演化

Study on Rate Dependent Damage Evolution of Cement Mortar

实验结果表明，水泥砂浆在受力变形中的损伤演化是率相关的，因此，类似于位错运动的热激活机制；给出了水泥砂浆的率型损伤演化律．

The experiments show that the damage evolution of cement mortar is a rate dependent process under impact and quasi static loading. A rate dependent damage evolution law is suggested on the basis of a thermo activated mechanism.
