Radiation from Arbitrarily Accelerating Dislocations in Anisotropic Solids

We present a methodology for the study of the fields (stress, strain, velocity, displacement) radiated from an arbitrarily accelerating dislocation (screw or edge) in an anisotropic solid. For general symmetry, the Laplace transforms in time and space lead to the solution of a sextic algebraic equation. The wave-front behavior is obtained by a geometric interpretation of the Cagniard-de Hoop contour (used for the inversion of the transforms).
