Atomistic studies of the elastic properties of metallic Bcc nanowires and films

Abstract
In this paper a systematic study of the surface influence on the elastic properties of nanosized iron and tungsten wires and films is performed. Single crystal

defect-free nanowires and nanofilms are examined through molecular statics simulations, and the concepts of surface energy and third order elastic constants are

used in an attempt to describe the elastic properties. For structures where the relaxation strains are small in magnitude, reasonable agreements between the continuum

mechanical solutions and the simulations are obtained. For structures where the relaxation strains are significant it is shown that third order elastic continuum theory

is not sufficient to describe the elastic properties; in... (More)
