Abstract
We investigate numerically the shape of cracks obtained in hydraulic f racturing at constant pressure using a square-lattice beam model with disorder. We consider the case in which only beams under tension can b reak, and discuss the conditions under which the resulting cracks may develop fractal patterns. We also determine the opening volume of the crack and the elastic stress field in the bulk, quantities that are ac cessible experimentally.
