Description
In recent years, newly available experimental measurements of grain boundary motion in polycrystalline materials challenge the assumption of the Herring angle condition at triple junctions (a well-known force balance condition). One of the proposed explanations for the discrepancy between these experimental data and the traditional model is the presence of triple junction drag. In this talk, I will review the sharp-interface model (curvature motion of networks with triple junction drag) and present a novel phase-field approximation for it.
