以损伤变量为特征的岩石损伤理论研究进展

Research Devlopment of Rock Damage Theory Characterized by Damage Variables

从损伤变量定义的方法入手,讨论了基于不同的损伤变量定义方法及其相应的损伤模型。通过对损伤变量从纯唯象的定义方法到考虑裂纹细观的定义方法的探讨,说明了损伤模型的发展趋势。

Starting with the definition of the damage variables, the definition methods of damage variables and their related damage models are discussed. Through the discussion of the definition methods of damage variables from the method of simple phenomena to the method of considering microphone of crack, the development trend of the rock blasting damage theory is summarized.
