摘要：

The ring-core method is the semi-destructive experimental method used for evaluation of the homogeneous and non-homogeneous residual stresses. In this paper, the integral equation method to quantify non-uniform residual stress fields is discussed. Therefore, correctly determined and properly used calibration factors a(ij) and b(ij), necessary for the residual stress measurement by the ring-core method, are essential. The finite element method is used for the simulation of residual states of stress and to calculate relieved strains on the top face of the core, which are necessary for the subsequent calibration factors' determination.
