Abstract
In the present work an experimental method is developed for residual stress evaluation in medium thick plates. On the basis of the incremental hole-drilling technique, a method to resolve the in-plane residual stresses through the plate thickness is given. An analysis of the hole-drilling configuration is carried out, resulting in a configuration which optimizes the stress calculation accuracy. Moreover, it is estimated that conventional milling can be applied without affecting the accuracy of the method. Finally, the results of a comprehensive stress calculation error analysis are presented.
