Abstract
We calculate to first order the static stress distribution around cracks which are slightly perturbed from semi infinite straight planar geometry and are subject to type I loading. We find that both in-plane and out-of-plane perturbations give rise to local stress distributions which tend to suppress the deviations in the posterior (quasistatic) propagation of the crack.
