Abstract

This paper addresses the accuracy of the experimental J estimation equation based on the load-CMOD curve for SE(B) specimens, proposed by Kirk and Dodds. Systematic investigations, based on 2-D FE analysis with realistic stress strain data for various materials, show that the estimation equation by Kirk and Dodds is not sensitive to the material but shows a large error for very deep cracks such as a/W=0.7. Based on slip line field analysis, a slight modification to the J estimation equation by Kirk and Dodds is given, then provides consistent results for all possible crack lengths.
