摘要/Abstract

摘要： 以岩块的各向同性弹性损伤为例，提出了一种基于最小耗能原理建立损伤演变方程的新思路，并推导得到了岩块在单向压缩下的损伤演变方程及临界损伤值。

关键词: 最小耗能原理, 损伤演变方程, 损伤临界值

Abstract: Taking the isotropic elastic damage of rock as example, a new approach of establishing a damage evolution equation based on the principle of least energy consumption is proposed and the damage evolution equation and critical damage value of rock under uniaxial compression are deduced.

Key words: Least energy consumption principle, Damage evolution equation, Critical damage value
