Résumé : 

This work deals with a numerical simulation of the friction stir welding FSW process of alloy material AA2195-T8. A 3D transient thermal model for simulating the heat transfer phenomena in the welding phase is applied. In this model, the FSW tool is considered as a circular heat source moving in a rectangular plate having a cooling surface and subjected to nonuniformandnon-homogeneousboundaryconditions.ThethermalproblemissolvedusingthefiniteelementmethodaspartofaLagrangianformulation.TheobtainedresultsallowustodeterminethemaximumvalueofthetemperatureintheNuggetzoneoftheweldedjoint.Duringthisprocess,thethermalcycleandthetemperaturedistributionweredeterminedfordifferentvaluesoftheweldingprocessparameters.Theobtainednumericalresultsareingoodagreementwiththeoneavailableintheliterature.
