Analysis of a prototypicalmultiscale method coupling atomistic and continuum mechanics
Published online by Cambridge University Press: 15 August 2005
Abstract
In order to describe a solid which deforms smoothly in some region, butnon smoothly in some other region, many multiscale methods have recentlybeen proposed. They aim at coupling an atomistic model (discretemechanics) with a macroscopic model (continuum mechanics).We provide here a theoretical ground for such a coupling in aone-dimensional setting. We briefly study the general case of a convexenergy, and next concentrate on a specific example of a nonconvex energy, the Lennard-Jones case. In thelatter situation, we prove that the discretization needs to account inan adequate way for the coexistence of a discrete model and a continuousone. Otherwise, spurious discretization effects may appear.We provide a numerical analysis of the approach.
