ROCK FRACTURE PROCESS ZONE AND ITS INFLUENCE ON MODE Ⅱ FRACTURE BEHAVIOR
(Department of Resources Exploitation,Central South University of Techology,Changsha 410083)
Abstract: On the basis of that rank material usually has。larger fracture process zone，a new
fracture criterion which is different Tram that of linear elastic fracture theory was presented. Un this ha-615，the fracture behavior and influencing factors under mode Ⅱ or compressive shear loading were in-vestigated
