1D Modelling of internal oxidation phenomena with X-FEM

Abstract

The simulation of simultaneous diffusion and precipitation of a chemical element during internal oxidation phenomena is presented here, from X-FEMmethod. This technique seems to be really appropriate when solubility products are very low, or even almost null. In this case, a precipitation front appears and should be properly represented by the numerical simulation. TheX-FEM method is then of strong interest, since it allows to know precisely the position of thefront all the time of simulation, without remeshing. © AFM, EDP Sciences 2010.
