    JIc 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 KIc in Charpy-sized, deeply cracked specimens loaded slowly in bending.
