A microstructure-sensitive electro-chemo-mechanical phase-field model of pitting and stress corrosion cracking
<|reference_start|>A microstructure-sensitive electro-chemo-mechanical phase-field model of pitting and stress corrosion cracking: An electro-chemo-mechanical phase-field formulation is developed to simulate pitting and stress corrosion in polycrystalline materials. The formulation incorporates dependencies of mechanical properties and corrosion potential on crystallographic orientation. The model considers the formation and charging dynamics of an electric double layer through a new general boundary condition for the solution potential. The potential of the model is demonstrated by simulating corrosion in polycrystalline materials with various grain morphology distributions. The results show that incorporating the underlying microstructure yields more extensive defects, faster defect kinetics, and irregular pit and crack shapes relative to a microstructurally-insensitive homogeneous material scenario.<|reference_end|>
