Abstract
SIFs on a circular crack due to distributed tractions are given by singular integrals over the crack surface. Surrounding the singularity point by a s mall (almost) semicircular region, we evaluate the singular part of the int egral in a universal closed form. This leads to an accurate and numerically trivial procedure. It is also extended to moderately non-circular cracks.
