Research Abstract |
In this study, non-contact residual stress evaluation method was developed by using image processing technique with digital camera. The validity of the proposed method was verified by applying to the bead on plate problem that is a basic welding test. In addition, the results of the in-plane deformation and the out-of-plane deformation obtained by the proposed method are good agreement with those of digital caliper and laser displacement meter.
