摘要	In this paper, an atom-continuum coupled model for thermo-mechanical behaviors in micro-nano scales is presented. A representative volume element consisting of atom clusters is used to represent the microstructure of materials. The atom motions in the RVE are divided into two phases, structural deformations and thermal vibrations. For the structural deformations, nonlinear and nonlocal deformation at atomic scales is considered. The atomistic-continuum equations are constructed based on momentum and energy conservation law. The non-locality and nonlinearity of atomistic interactions are built into the thermo-mechanical constitutive equations. The coupled atomistic-continuum thermal-mechanical simulation process is also suggested in this work.
