摘要：
A general method for the numerical solution of the singular integral equation describing the curved crack problem is presented. The basic idea is the approximation of the dislocation function by a polynomial divided by a weight function. Combined with the collocation method this leads to a simple algebraic procedure for the calculation of K-factors. Several examples demonstrate the applicability of the method.
