A one-step application of the finite element (FE) method is suggested as a means for the engineer's routine determination of stress intensity factors in linear fracture mechanics for complicated non-symmetric geometries with three-dimensional states of stress and curved crack fronts. The vector-valued influence functions (Green functions) used here are a special kind of weight functions. Mode separation is inherent to the present procedure. Numerical examples demonstrate the versatility of the method.
