Abstract

The evaluation of stress intensity factors for surface flaw problems and, in particular, semi-elliptical surface cracks in cylindrical pressure vessels has been developed using the finite element alternating method. Some examples include the interaction effects due to multiple internal longitudinal surface cracks in cylinders as recommended for analysis in the A. S. M. E. Boiler and Pressure Vessel Code (Section XI). For each crack geometry, several loading cases are considered including internal pressure and polynomial pressure loadings from constant to fourth order. The problem of a single circumferential crack in a cylinder is also investigated.
