Efficient Computational Techniques for the Analysis of some Problems of Fracture in Pressure Vessels and Piping.

Abstract

Results of (i) a numerical investigation, based on an energy consistent moving-singularity dynamic finite element procedure, of fast crack propagation in a finite plate; (ii) numerical simulation of experimental data on fast crack propagation and arrest in a double-cantilever-beam specimen; and (iii) stress-intensity factor solutions in a thermally shocked cylindrical vessel containing an inner surface (meridional) elliptical flaw, are presented. Comparison of these results with other available solutions, and pertinent discussions, are included. (Author)
