Title: Numerical Simulation of The Mechanical Properties of Nanoscale Metal Clusters Using The Atomistic-Continuum Mechanics Method
Author: Chiang, K.-N.; Chou, C.-Y.; Yuan, C.; Wu, Chau-Chung
Abstract: Atomistic Continuum Mechanics Method, Young’s Modulus, Poisson’s Ratio, Lithium, FEM, ACM,A novel atomistic-continuum method (ACM) based on finite element method (FEM) is proposed to numerically simulate the nano-scaled Poisson’s ratio and Young’s modulus effect of Lithium (Li) body-centered cubic (BCC) structure. The potential energy between Li atoms is described by the Morse potential function [1]. The pre-force effect will be discussed due to the different Li lattice length between experimental lattice constant and diatom distance from Morse function. Moreover, the size effect of the nano-scaled Li cluster will be introduced.
