3D MD model combined with FEM

Abstract

A three dimensional molecular dynamics (MD) model combined with a finite element method (FEM) is proposed for the analyses of micromachining process. In the connecting area of the model, the displacement of a node in FEM model is given by the average displacement of atoms around the node in MD model. On the other hand, the force generated at a node in FEM model is divided among the atoms around the node in MD model. The both models are connected well by the method proposed.
