Abstract

We investigate several issues connected with bridging methods for AtC coupling. We study different coupling approaches, using various blending models, as well as the influence of the parameters of the models on the results. One approach we focus on is the use of the Lagrange multiplier method for enforcing constraints on the atomistic and continuum displacements in the bridge region. In addition, we investigate a multiple-neighbor interaction, applying a number of boundary treatments in the atomistic region.
