Abstract

Weld residual stresses are affected by phase transformation of low-alloy steels. When phase transformation occurs, transformation plasticity occurs in addition to transformation expansion. Conventional predictions of welding residual stress using the finite element method often consider only transformation expansion, and there are few cases in which transformation plasticity is taken into factor. In this study, welding residual stress analysis that factors in transformation plasticity was performed to verify the effect of transformation plasticity on welding residual stress. The results show that the prediction accuracy of welding residual stress due to transformation expansion of low-alloy steel is improved by factors in transformation plasticity.
