Further results on rectilinear line cracks and inclusions in anisotropic medium

The Fredholm integral equations of the second kind are obtained for a system of arbitrarily spaced and oriented cracks and embedded in a two-dimensional infinite anisotropic solid for the first and second fundamental problems. The stress intensity factors K 1 and K 2 are derived; they are expressed in quadratures from the specified boundary conditions and the corresponding solutions of the integral equations. Numerical calculations are performed for specific crack configurations where the algorithm employed gave high convergence.
