... displacement discontinuity element is implemented at the crack tip. Also, maximum principal stress criterion is used to determine crack growth trajectory. Numerical results indicate that the high thermal stresses due to cold-water injection can lead to initiation and propagation of secondary crack growth...

... model of symmetric rock wegdes in a horizontal stress field has been utilized. A comparison between the results of an extension of a closed form solution proposed by Bray(1981), and numerical analyses with Displacement Discontinuity elements (Crouch, 1976), are presented. These analyses indicate...
