Peridynamics (PD) is a continuum theory that employs a nonlocal model to describe material properties.it this context, nonlocal means that continuum points separated by a finite distance may exert force upon each other A meshless method results when PD is discretized with material behavior approximated as a collection of interacting particles. This paper describes how PD can be implemented within a molecular dynamics (MD) framework, and provides details of an efficient implementation. This adds a computational mechanics capability to in MD code, enabling simulations at mesoscopic or even macroscopic length and time scales. (C) 2008 Elsevier B.V. All rights reserved.
