摘要

This paper presents a combined system based on DSPI and local heating, which allows the evaluation of residual stresses. To determine the residual stress values, a finite element analysis (FEA) of the thermomechanical process is carried out. The feasibility of this approach is demonstrated by comparing the results obtained from measurements in a preloaded specimen and the stress values introduced in it.
