Modélisation des couplages fluide/solide dans les procédés d'assemblage à haute température

Abstract

A numerical tool for the simulation of the Friction Stir Spot Welding process is developed. The model is based on a fluid/solid coupling which describes the state of the material in the structure. The model includes the P1+/P1 finite-element, developed with a strong thermomechanical coupling, both for fluid and solid behaviours. The coupling, associated with an Arbitrary Eulerian Lagrangian approach, is implemented in a new option of the finite element code SYSWELD®. We present here a first simulation of the Friction Stir Spot Welding process. © AFM, EDP Sciences 2011.
