Abstract

A procedure to determine the ductile fracture toughness value J_Ic, the value of the J integral at incipient crack growth, is described. The procedure was developed by the working committee of ASTM Task Group E24.01.09 on Elastic-Plastic Fracture under Committee E-24 on Fracture Testing. The principal goal of this report is to present a procedure for J_Ic determination that may be used as a basis for an ASTM standard on elastic-plastic testing. Although this procedure is described in terms of the multiple-specimen technique, any single-specimen method can be used as long as a good correspondence exists between the crack extension as measured by the heat tinting technique and that measured by single-specimen methods.
