Abstract

Part I describes plane strain yielding, stresses and fracture about notches and cracks in terms of flow and fracture stresses and crack tip radii and, using generally appropriate dimensionless variables, it presents a graph of sub-surface fracture loci and a Table (I) from which notch and crack failure can be computed.

Part II, which may be read independently of I, employs the table, a definition of fracture stress, a very simple postulate of invariance of a fracture stress parameter, and the yield strength to compute fracture toughness as a function of test temperature, tempering temperature, and strain-rate, for comparison with corresponding examples from the experimental work of others, as a demonstration of the utility of the approach.
