An inclined fracture in an infinite rock mass is under uniaxial compressive stress of 50MPa. The inclination of the fracture is 45°. The elastic properties of the rock mass and the fracture critical strain energy release rates are the same as in Example 1. The contact properties of the fracture surfaces are:
The fracture is found to propagate in mode I in the direction nearly parallel to the far-field stress.
