Abstract
In the present paper, researches which investigate the influence of surface energy and surface stresses on mechanical behaviors in nano-sized elastic domains are reviewed. A dynamic equilibrium relationship involving surface stresses and bulk stress on a general curved interface is firstly derived. Surface wave propagation and stress distribution around a prismatics dislocation loop existing near an interface are discussed. Furthermore, a contact analysis based on three-dimensional theory of elasticity and a nano-adhesion theory considering surface stresses is presented. Green function considering surface stresses as a tool for analyzing surface defects, steps, undulation, 2D and 3D islands on surfaces is derived in the framework of the theory of elasticity.
