Elastic-plastic analysis of edge-notched panels subjected to fixed grip loading

Abstract An expression for the mode I stress intensity factor for single edge-notch panels under fixed-grip loading is derived using known solutions for uniform tension and pure bending cases. An expression for the stress distribution along the fixed boundary is also derived. Then, using this stress distribution, an approximate expression for the J -integral is derived. The stress intensity factor and the J -integral solutions are compared with finite-element analysis results.
