摘      要：In this study, residual stresses in heat treated specimen were measured by using ESPI (Electronic Speckle-Pattern Interferometry) combined with the hole-drilling *** specimen, made of SUS 304 austenitic stainless steel, was quenched and water cooled to room *** simulation using a hybrid FDM/FEM package was also carried out to simulate the heat treatment *** a result, the thermal stress fields were obtained from both the experiment and the numerical *** comparision of stress fields, results from the experimental method and numerical simulation well agreed to each other, therefore, it is proved that the presented experimental method is applicable and reliable for heat treatment induced residual stress measurement.
