Over the years, the phase-field method has become the method of choice for simulating microstructure evolution at the micro- to mesoscopic scale. Applications range from solidification to solid state transformations, and include couplings with elasticity, plastic relaxation, twinning, piezoelectricity, magnetism... The symposium shall review actual developments in this rapidly growing field with special emphasis on the interactions between the microstructure and mechanical loading. Multi-scale approaches including or based on a phase-field model are of interest as well. Materials in focus are metals and ceramics; however applications to soft matter and polymers are welcome to explore synergetic approaches.
