    Abstract

    Mixed mode fracture I/III toughness determination for ductile materials currently uses an empirical equation for the blunting line. A modification based on the use of experimental measurements of the critical stretch zone width (SZWc) for the blunting line is suggested. A further modification, also based on SZWc measurements, that gives a notch root independent mixed mode I/III fracture toughness from a single specimen is described. Mixed mode fracture toughness tests on Armco iron, CP titanium, mild steel, and nickel have been carried out to evaluate these methods.
