Extended abstract It is well known that performances of materials are determined by atoms and various scale microstmctures composed by them.The behaviors of materials and structures in scales larger than micrometer is described by macro-continuum model, while in nano-scales, the behaviors can be described by atomistic models.In order to study the behaviors of materials in micro-nano scates, the coupled model of connecting atoms with continuum is needed.In this paper, an atomistic-continuum coupled model for thermo-mechanics behavior of materials is systematically presented [2].The main results are following.
