T-Stress and Stress Intensities for the Interface Cracks in Some Specimen-Relevant Geometries

Based on a solution to interface cracks obtained earlier by the author, T-stress, energy release rate and stress intensity factors are derived in closed form for some specimen-relevant configurations (four-point bend, one-sided tension and peel-tension) with an interface crack between two elastic layers. The results may be useful for the fracture toughness testing of bimaterial interfaces.
