英文摘要	In view of the importance of surface stress in controlling mechanical responses of nanoscale structures,the effects of surface stresses on the elastic field around a circular hole in an elastic half plane were analyzed.The complex variable function method was adopted to derive the fundamental solution to the contact problem.The deformation caused by the uniformly distributed traction on the plane surface and the surface stress along the cavity boundary was analyzed in detail.The results reveal strong size-dependence of the stress field and the surface deformation on the surface stress,and the surface displacement directly above the circular hole is a function of the surface stress.
