The stress or strain field near a crack-tip in a thermally-loaded structure has the HRR singularity and its amplitude is determined by the path-independent j-integral. The j-integral is an extension of Rice's f-integral and is related to the energy-release rate in thermal stress held. The finite ele

Three-dimensional, elastic and elastic-plastic finite element analysis of small surface cracks was performed. The elastic analysis is in good agreement with other solutions. For a round surface with a radius equal to six times the crack depth, the K at the surface is about 4% higher than the K for a
