Abstract
Multiscale discrete element model adapting information on material microstructure is introduced. Modeled structure is represented by a set of tetrahedral elements bound by their faces. Each element has an associated atomic sample, which represents atomic structure of the element. All element properties are determined from molecular dynamics simulation of its associated sample. Therefore, none of the specific properties of the material are needed aside from its atomic composition and microstructure. The chapter focuses on elastic behavior of modeled structures. Comparisons of the results obtained using multiscale discrete element simulation with molecular dynamics data and known macroscopic material properties show fairly good accuracy of the proposed model.
