Abstract

This paper presents stress-intensity factors for semi-elliptical cracks of various geometries located at the outer or inner surfaces of pressurized or thermally shocked thick walled cylinders. The stress-intensity factors were directly computed through a three-dimensional, embedded singularity, hybrid-displacement finite element procedure. This model is based on a modified variational principle of total potential energy with three independently assumed field variables. The developed procedure has been checked for its convergence properties by solving problems such as embedded penny-shaped or elliptical cracks in infinite domains, for which analytical solutions are available. Through this study, an optimum size of the elements near the crack front, as compared to the ″characteristic length″ of the crack, is also derived.
