Abstract
Residual stress is a critical determining factor for the strength and service life of welded structures. Owing to its importance, a number o f researchers have worked to estimate the residual stresses in the wel dments. In the present work the residual stresses in butt welds were e stimated using an elasto-plastic nonlinear finite element model. The t emperature distribution was calculated by a finite element model using adaptive grid techniques. The temperature dependent mechanical proper ties were considered. The results were compared with the experimental results available in the literature. Copyright (C) 1996 Elsevier Scien ce
