Abstract:

The relationships between fracture toughness, flow stress and material ductility were studied for the high strength steels, D6AC and 300M, each heat treated to 3 strength levels. In addition to the experimental part of the study which included biaxial ductility test, notch-tensile test and fracture toughness test the theoretical studies, to develop an analytical basis for correlation between fracture toughness and flow properties of solids, were continued. The fracture ductility was found to decrease significantly on going from the uniaxial stress state to the plane strain stress state to the balanced biaxial condition. A strong influence of the surface finish was noted. Modified author abstract
