摘要
从花岗岩弹性模量随温度的变化规律入手 ,提出了热损伤的概念 ,在此基础上导出了热损伤演化方程和一维TM(热与力 )耦合弹脆性损伤本构方程 ,并讨论了损伤能量释放率随温度的演化规律。
The concept of thermal damage is introduced based on the relation of elastic modulus and temperature for granite. The thermal damage evolution equation and one dimensional TM coupled elasto brittle damage constitutive equations are established. And the release rate of damage energy with temperature is discussed.
