Measurement and Theory of the Dependence of Hardness on Residual Stress

Abstract

The Rockwell C hardness (Rc) was measured as a function of position on the three steel rings cut from tubes with different amounts of autofrettage. These rings had different residual stress profiles through the wall that were measured using an ultrasonic technique. An experimental correlation between residual stress and Rc was obtained. In order to model the effects of residual stress on the measured hardness, the Tresca (linear) and the von Mises-Hencky (power) yield criteria were utilized within a model given by Shaw, Hoshi, and Henry that depicts the stress state within a spherical indenter. The von Mises- Hencky method was more successful in matching the data.... Hardness, Residual stress, Yielding criteria, Autofrettage, Ultrasonics
