Residual Stresses and Distortion in Weldments: A Review of the Present State-of-the-Art
The paper first discusses how practicing engineers cope with problems relating to residual stresses and distortion. Two types of analyses are needed. One is to analyze how they are affected by design and fabrication parameters and the other is to analyze the effect of residual stresses and distortion on the service behavior of welded structures.
The paper discusses methodologies of analyzing residual stresses and distortion in weldments and how they have been developed. Trends in recent studies, especially those using computers, are presented.
The paper then presents a summary of analytical and experimental studies made at M.I.T.
