Finite Element Modeling of a Diffusion-Controlled Phase Transformation in Thin Film
We derive and implement a finite element (FE) model for stress-mediated diffusion and phase transformation in thin films. The partial differential equations governing diffusion and mechanical equilibrium are of different order. To ensure uniform convergence of the FE method, the continuity class of respective interpolation functions must be different. We test our implementation on a ID problem and demonstrate the validity of the approach.
