JIC Measurement Point Determinations for Hy130, CMS-9, and inconel 718

Abstract

Determination of the elastic-plastic fracture toughness for three medium strength materials of varying ductility has been carried out. The materials in decreasing ductility are HY130 Steel, CMS-9 Steel, and Inconel 718. A survey of measurement-point techniques for J sub Ic has been incorporated in the study to evaluate the effect of ductility on the determination of both an elastic-plastic fracture parameter and a fracture measure for direct estimation of the elastic fracture toughness K sub Ic.
