R-Curve Approach to Fracture Toughness Analysis of Some GLARE Grades (BE2040Subtask 5.1-d)

摘要

This report deals with the residual strength prediction for GLARE 2 3/2-0.3,GLARE 3 3/2-0.2, GLARE 3 3/2-0.3 and GLARE 4 2/1-0.3. The objective is to investigate the use of the fracture mechanics based R-curve concept, similar to that used for metals, to predict the residual strength of forementioned materials.
