Abstract

In order to incorporate the mechanical behavior of ferroelastic phase into the stress analysis of solid oxide fuel cell in consideration of elastic, creep, thermal and reduction strains, we propose a mathematical model to predict the formation of ferroelastic phases in crystal grains of La0.6Sr0.4Co0.2Fe0.8O3-δ. The phase-field model equipped with the elastic energy is introduced to realize the morphology formation of ferroelastic phases in a crystal grain. By using the developed mathematical model, some numerical examples are performed to reproduce the deformation-induced nucleation and growth of ferroelastic phases of La0.6Sr0.4Co0.2Fe0.8O3-δ.
