The solid-electrolyte interface kinetics nonlinearly depends on the thermodynamic driving force and can be accelerated by mechanical straining according to the film rupture-dissolution mechanism. A number of examples in two- and three- dimensions are demonstrated based on the finite element-based MOOSE framework. The model successfully captures the pit-to-crack transition under simultaneous electrochemical and mechanical effects. The crack initiation and growth has been demonstrated to depend on a variety of materials properties. The coupled corrosion and crystal plasticity framework also predict the crack initiation away from the perpendicular to the loading direction.application/pdfenCreative Commons Attribution 4.0 Internationalphase field modelcoupled electrochemical and elastoplastic behaviorpit-to-crack transitioncrystal plasticityArticle - Refereedhttps://doi.org/10.1088/1361-651X/acd1323151361-651X
