On the residual stresses in friction stir-welded parts: Effect of the geometry of the joints

Research output: Contribution to journalArticle

Abstract

Residual stress state is a fundamental aspect of welded joints, especially when complex geometries are considered. In this article, the residual longitudinal stresses in friction stir-welded joints were measured. In particular, different joint configurations were taken into account, namely butt joints, T, and lap ones, the latter being definitively interesting case studies with reference to applications in the transportation industries and, particularly in the aerospace industries.
