Title: Comparison of various methods of measuring ic on small precracked bend specimens that fracture after general yield
Abstract: An experimental investigation into the measurement of fracture toughness on small precracked bend specimens after general yield is described. Six parameters are compared on the basis of their accuracy and utility in predicting KIc. The parameters are: (i) the on-load crack tip opening displacement, COD, (ii) the lateral (notch root, crack tip) contraction, NRC, (iii) the angle of bend, (iv) the stretch zone, (v) the J integral, and (vi) the equivalent energy. The materials used were. for the most part, A533B and 4340 steels.
