Interfaces in materials can be separated into various categories: grain boundaries, twinning boundaries, phase transformations, ferroelectric domain walls, and magnetic domain boundaries. The mechanics and the motion of these interfaces play a fundamental role in determining the overall physical properties of a material, e.g. stiffness, strength, plasticity, dielectric constant, piezoelectric constant, coercive field, and magnetic susceptibility. As such, material design for different applications such as in infrastructure is heavily influenced by the presence and the properties of interfaces. This symposium invites abstract submission on topics related to improving our understanding of the influence of interfaces in materials on overall properties within the following categories (including theoretical, computational, and experimental approaches):

– Understanding the role of interfaces in extreme environments through theoretical and experimental methods

– Modeling grain boundary anisotropy of energy and mobility in metals and ceramics

– Computational modeling of grain boundaries in microstructure (using, e.g., atomistic, dislocation dynamics, or phase field methods)

– Experimental characterization of grain boundary evolution during high temperature processes such as sintering

– Improving our understanding of the effect of interfaces on material properties

– Interactions of interfaces with defects – Modeling domain walls in ferroelectrics (using, e.g., phase field methods, continuum mechanics, or atomistics)

– Experimental observation of ferroelectric domain walls using, e.g., scanning probe microscopy

– Understanding the evolution of magnetic domains (using, e.g., phase field methods or continuum mechanics)
