Layer Growing/Removing Method for the Determination of Residual Stresses in Inhomogeneous Spheres

Abstract

A generalized algorithm of the layer growing/removing methods is presented for computing residual stresses in case of the multilayered hollow sphere from strain measurements on the free stationary surface or from X-ray diffraction measurements on the sphere´s moving surface. The algorithm is valid for layer growing/removing on the outer or inner surface of the sphere and is of interest first of all in the study of residual stresses in coatings and surface layers generally. The suggested algorithm is programmed for PC. Two examples of application are presented.
