Modélisation numérique avec apport de matière du soudo-brasage des assemblages hétérogènes acier/aluminium

2007

This study deals with the numerical simulation of heterogeneous brazing of steel / aluminium alloy sheets by CMT process. The difference between the linear expansion coefficients of these materials generates high deformations and residual stress. The addiction of brazing material is simulated. A validation the model is made in the simplest case of a sheet of aluminium alloy with a brazing bead. Comparisons are made between numerical and experimental results on out-of-plane displacements of steel / aluminium assembly.

Etude numérique et expérimentale de l'assemblage acier aluminium par soudo-brasage

2006

Dans cet article nous étudions le soudo-brasage de tôles d'acier et d'aluminium (par la technique CMT, assemblage à clin). Ces métaux ont des coefficients de dilatation thermique différents, ce qui provoque des déformations, d'où des contraintes mécaniques élevées. Des expériences sur des éprouvettes, une simulation numérique thermomécanique sont menées en parallèle afin de mieux comprendre ces aspects thermiques et mécaniques dans le but de minimiser la déformation de l'assemblage.
