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 I sub c 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 toughness measure for direct estimation of the elastic fracture toughness K sub I sub c.
