The problem of a plane crack in an infinite solid under normal internal pressure is formulated to result in an integral equation for the unknown normal stresses on the plane of the crack. Once these stresses are determined the stress intensity factor, KI, around the crack edge and the normal displacements of points inside the crack region are obtained numerically. The crack contour shape and the normal loading of the crack can be arbitrary. In this paper the integral equation is solved numerically and the stress intensity factor, KI, is obtained for cracks subjected to uniform and linearly varying normal pressure and having various convex contour shapes.
