A method is presented for obtaining directly the elastic stress distribu¬tion in a thin, finite-width orthotropic plate with a central crack. The solu¬tion, which was obtained by the use of finite Fourier transforms, involves the solving of an integral equation for the crack opening;the stresses can then be computed by simple quadrature. The solution is valid as long as the plate width is at least twice the crack length. It is shown that the stress inten-sity factor is independent of the orthotropy of the material.
