A numerical technique has been developed for determining stress intensity factors in cracked anisotropic plates of finite geometry. Using complex variable methods an exact solution is derived for the problem of unit loads applied to a cracked infinite anisotropic plate. This fundamental solution is used with the boundary-integral equation method for analysis of plates of finite geometry. Numerical results are obtained for center-cracked and double-edge cracked finite width tension specimens using material properties representative of a family of advanced fiber reinforced composite laminates. For these geometries the numerical results indicate that the isotropic stress intensity factor serves as a good approximation for anisotropic materials. Author, modified-PL
