文摘Moire interferometry method is introduced to study the feasibilities of J integral as a plastic singularity parameter at the tip of the notch in the welded joints. The results show that J dominance in most studied cases is not validated in v and u displacement fields. Therefore, it can be concluded that J-integral as controlling parameter used to estimate the safety of welded structures is not always valid.
