摘 要：本文对Liebowitz非线性能量法进行了修正和改进,而且将作者的方法与由ISRM获得的岩石材料的非线性断裂韧度值以及其它方法进行了比较。结果表明,作者的方法和ISRM工作组的建议方法以及由Work方法所得值是基本相近的。
Abstract: Liebowitz's nonlinearity energy method has been modified and improved by authors in this paper and thepresent method is compared with nonlinear fracture toughness values of rock material obtained from ISRM method and other methods. Results show that our method is compatible both with the suggested methods of the working group within ISRM and with values from Work's method as well.
