This paper describes a study of the ability of the DUD technique to measure the spatial distribution of residual stresses. A two dimensional finite element model of a metal plate has been generated together with a representative state of residual stress. A simulation of the DHD technique is then carried out to provide a series of measurements of the residual stress which can be compared with the known residual stress. This simulation allows the effect of the varying trepan diameters on the accuracy of the DUD technique to be explored.
The results of the simulation show that the DIM technique can be used to measure residual stress with a high accuracy, but the increase in the trepan diameter introduce some errors. Suggestions and techniques for reducing these errors are presented.
