The Deduction and Application of Correction Formulas of Three-Dimensional Residual Stress with Layer Stripping Method

Abstract:

In order to measure 3D residual stress accurately with layer stripping method, this paper proposes a series of elastic mechanics hypothesis and deduces a set of correction formulas based on the model of cylinder with limitless length. The formulas are expressed as discrete form. When the thickness of removed layer is infinitesimal, the discrete formulas agree with the existing integral formula. This paper also gives an engineering example and verifies the importance of residual stress correction.
