Two methods are proposed for identifying plan e cracks in an anistropic elastic medium, based either on the use of a "nonreciprocity" functional or on the non-classical method of boundary integral equations and leading to the solution of certain transcendental equations.

โฆ Synopsis
The problem of an arbitrarily-o~ent~ plane crack in an anisotropic elastic slab is considered. Through the use of a Fourier transform technique, the problem is reduced to a system of simultaneous Fredholm integral equations of the second kind. Once these integral equations are solved, relevant quantities such as the crack energy can be readily computed. Numerical results pertaining to the stability of a plane crack in a particular elastic slab are given.
