Abstract: Nonlocal continuum and atomistic models are used in many scientific and engineering applications, where material dynamics depends on microstructure. The numerical solution of nonlocal models might be prohibitively expensive; therefore, concurrent multiscale methods have been proposed for efficient and accurate solutions of such systems. These methods employ nonlocal models in parts of the domain and use local, macroscopic, models elsewhere. A major challenge is to couple these models at interfaces or in overlapping regions. This minisymposium invites contributions on coupling local and nonlocal continuum models and concurrent multiscale methods for atomistic-to-continuum coupling. Related domain decomposition methods are also considered.
