The Friction Stir Processing (FSP) is an innovative surface engineering method,
considered as a green processing technique. A good physical understanding of the process can
be reached by the combined efforts of experimental examination and numerical modelling. In
this paper, a three-dimensional heat transfer model for FSP is presented. Then, a numerical
inverse method that allows to estimate the Coulomb friction coefficient µ combining
experimental test, finite element simulations and optimization is developed.
Keywords: Friction Stir Processing; Heat Transfer Model; Finite Element Simulation; Optimization.
