Popis:	The influence of the surface stress on the local buckling of an infinite plate with a circular nanohole under the uniaxial remote tension is investigated. The critical (Euler) load corresponding to the buckling is sought by the Ritz method in framework of the linearized Karman set of equations under the symmetrical and antisymmetrical form of the deflection. Numerical calculations are performed for different elastic properties of the surface. It is shown that taking into account the surface stress decreases the critical load in both cases and the symmetrical form of buckling occurs before the antisymmetrical one.
