Abstract
Abstract A tentative test procedure for the determination of the plane strain-crack growth resistance JI-R curve for metallic materials is presented. This procedure was prepared by a Working Group of ASTM Committee E24.08.03. It was evaluated with a round robin test program on HY130 steel, conducted in 1980 to 1981. The results of the testing program were reported in a companion paper, and the experiences were incorporated in this procedure. The procedure is written for the elastic compliance method of developing the plane strain JI-R curve. Recommended specimens are the pin-loaded compact and the three-point bend specimens. Details regarding apparatus, specimen preparation, test system calibration, testing, calculation of J and crack extension, and data qualification are specified.
