Abstract

The initial strain distribution (ISD) method is applied to the evaluation of the residual stress in cladded plates with three different heat treatments. The experimental methods are explained and details for the application of the interpretation procedure developed in Part I are provided. The ISD allowed the complete residual stress field of the plates to be obtained and the effect of the heat treatments in the mitigation of the residual stress peaks to be verified. The obtained results make it possible to predict the residual stress field for any body that can be extracted from the plates by any procedure that does not introduce other sources of initial strain.
