JIc Measurement Point Determination for HY130, CMS-9, and Inconel Alloy 718
Determination of the elastic-plastic fracture toughness for three medium strength materials of varying ductility has been carried out. The materials in order of decreasing ductility are HY130 steel, CMS-9 steel, and Inconel Alloy 718. A survey of measurement-point techniques for JIc has been incorporated in the study to evaluate the effect of ductility on the determination of the elastic-plastic fracture parameter and subsequent estimation of the elastic fracture toughness KIc.
