Abstract

In this paper the FRANC3D (FRacture ANalysis Code for 3D Solids and Shells) program has been used to investigate the crack growth in a rock with multiple parallel cracks along an offset direction with respect to the in-situ stresses. The proposed technique only needs the discretization of the crack surface and the rock surface. The crack size during propagation is calculated using mode I stress intensity factor along the crack front. The crack propagation direction is determined using the minimum strain energy criterion. The fracture stiffness in 3-D crack systems is obtained.
