Abstract

J^Ic tests were performed using 10 by 12 mm cross section bend specimens of 4335 steel with yield stress in the range of 1200 MPa. Based on analysis of the results a simple, one-specimen, J-based test procedure is proposed which can be used to obtain the J equivalent of K^Ic in Charpy-sized, deeply cracked specimens loaded slowly in bending.
