✦ Synopsis

The problem under consideration is that of an elastically supported plate containing a through crack and subjected to out-of-plane symmetric bending. Using Reissner's theory, the problem is formulated for a specially orthotropic material, and is reduced to a singular integral equation. The resulting asymptotic crack tip stress field is identical to that of the plane elasticity solution. The problem is solved for a uniformly distributed or concentrated moment acting along the crack surfaces. The numerical results give the stress intensity factor, the bending moment along the crack prolongation, and the deflection along the line of the crack.
