Concept of the structural design has been shifted from the design-by-rule to the design-by-analysis in recent years. However, its shift is restricted within non-welded structure fields. A main reason may be due to lack of applicability for conventional stress measuring method to the finite element analysis (FEM) which is widely used in structural design. To solve this problem, the following new concept has been proposed. Displacements are measured through digital image pictures of a weldment before and after weld and eigen-stains are evaluated by the inverse analysis. Then displacements and residual stresses are estimated by the forward analysis. In this study, development of an image processing algorithm is attempted.
