Notes:
This paper presents a concurrent multiscale method for the stress analysis of solids usinga coupled meshless and molecular dynamic analysis. A new transition algorithm using transitionparticles was employed to ensure the compatibility of both displacements and their gradients. Theequivalent continuum strain energy density was obtained locally based on the atomic potential andCauchy-Born rule, and hence plasticity can be easily handled in not only the atomic domain but alsothe continuum domain. Numerical examples demonstrated that the present multiscale technique hasa promising potential of application to multiscale systems subjected to deformation
