A hierarchical multiscale coupling of the finite element method (FEM) and the discrete element method (DEM) is proposed to model coupled thermo-mechanical behavior of granular materials. The DEM is employed to model the thermo-mechanical responses of a representative volume element (RVE, a granular...
