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
Key words: fracture process zone shear fracture initiation angle
