This paper regards the analysis of structural behavior of Friction Stir Spot Welds (FSSW) in order to assess the failure mode and its dependence on mechanical properties distribution of the sheets material and on process parameters. In particular, in this paper is investigated the influence of non-axisymmetric anisotropy of material characteristics on static strengthand failure mode of FSSW. FSSW joint is analyzed by means of a complex 3D Finite Elements model, which allows to evaluate, in a parametric manner, the multifaceted internal geometry of the joint and the actual distribution of material mechanical characteristics after welding. Experimental tests allowed to verify the results and to calibrate the material model in the Finite Elementsanalyses.

Abstract
This paper regards the analysis of structural behavior of Friction Stir Spot Welds (FSSW) in order to assess the failure mode and its dependence on mechanical properties distribution of the sheets material and on process parameters. In particular, in this paper is investigated the influence of non-axisymmetric anisotropy of material characteristics on static strengthand failure mode of FSSW. FSSW joint is analyzed by means of a complex 3D Finite Elements model, which allows to evaluate, in a parametric manner, the multifaceted internal geometry of the joint and the actual distribution of material mechanical characteristics after welding. Experimental tests allowed to verify the results and to calibrate the material model in the Finite Elementsanalyses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
