Abstract

This paper presents a J - integral - tearing modulus analysis for thick plates containing uniform through cracks and subjected to biaxial bending stresses. The solutions are derived for various crack length ratios and applied stress conditions. They are useful for predicting stability of crack propagation in plates with limited plasticity in the vicinity of crack tip. The results are then applied to a carbon steel plate to predict the onset of crack growth instability. Similar applications may be made for other materials, plate geometry and stress conditions.
