Finite Element Method Applied to Mathematical Modelling of the Hydrogen Diffusion Process in Metals

Abstract:

This paper presents a finite element based method to modeling and simulating the hydrogen diffusion process in metals. Simulation has been done at microscopic level by taking into consideration a regular hexagonal prism as generic geometric model for the metallic grain. In solving the equations system associated to the model, the software package ANSYS10 has been used. Although this software is usually used for conductive heat transfer problems, it has been adapted to solve the hydrogen diffusion problem by identifying analogies between the heat transfer equation and the diffusion equation.

Keywords:
Hydrogen diffusion; metallic polycrystal; finite element method; mathematical modeling
