Method for Measurement of Residual Stresses using Eddy Currents

Abstract

Article is focused on using eddy current to measure of internal residual stress after milling. In presented article is described methodical process of identification residual stress in internal layers of the surface after machining of steel C45. Eddy current provides fast identification of residual stress directly in engineering areas without necessity to transfer samples in specialized laboratories. Presented article also describe procedure of evaluating measured values of deviation and its transformation to values of residual stress by conversion coefficients.
