| 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. |
