摘要
探讨物体形状变化而引起体内损伤演化的损伤力学课题 .给出了粘弹性时变体损伤力学的基本方程 ,并对时变体损伤场及位移场的时空变化规律以及时变效应作出定量分析 ,同时论证了岩土工程施工分析中应用时变力学理论与方法的必要性 .
The damage mechanics subject of damage evolution caused by body-shape time-varying is studied. The basic equations of viscoelastic time-varying damage mechanics are given at first, and then the temporal and spatial variation rule and time-varying effect of damage and displacement field of time-varying body are analyzed quantitatively. Finally, the necessity of applying time-varying theory in rock engineering construction analysis is demonstrated.
