Application of Finite Element Calculations to Residual Stress Measurements

Abstract

The use of finite element calculations is assessed as a means of analysis of the strain relaxation data from a measurement of residual stress by a material removal method. This application is important because it allows a greater flexibility of choice for specimen shape, materials, and experimental procedure than would be possible if only analytic or experimental calibrations are used. Three possible applications are described using the hole-drilling method as an example, and comparisons of calculated results and experimental measurements are presented.
