A coupled thermomechanical three-dimensional finite element model was developed for friction stir welding in the ABAQUS environment using Johnson–Cook material law and failure model. The temperature evolution during plunge, dwell moving stages of a welded 7050 aluminium alloy effect heat conduction by back plate were investigated. Results show that almost symmetrically distributes across cross-section, contour weld nugget zone presents V type shape after plunge stage. In stage, frictional...
Global mechanical behaviour, i.e. the true stress–strain curves, yield strength σs, hardening exponents n, and coefficients K, of friction stir welded plates, in which weld line lies either perpendicular or parallel to axis applied tensile force, is determined by using local constitutive properties base metal, heat affected zone nugget. The principle 'rule mixtures' adopted develop analytical models. Experimental data from Lockwood (2000 PhD Dissertation Department Mechanical Engineering,...
