LINEAR FRACTURE MECHANICS SOLUTIONS FOR ZERO AND RIGHT ANGLE NOTCHES

This paper presents a numerical procedure for the computation of stress intensity factors, which are used in linear fracture mechanics. The procedure is based on a conventional finite element stress analysis and thus can be carried out with any of the many standard programs that are available. A particular feature of this mehtod is that orthotropic materials and non-zero angle notches present non extra difficulties. Computed results are presented in the paper for: (1) Centre, edge and double edge cracks in a rectangular plate; (2) Multiple cracks in a rectangular plate; (3) Right angle notched plates. The accuracy of these results is expected to be better than plus or minus 5%. /Author/TRRL/
