Abstract: In this paper, the plane-strain buckling of compressible and incompressible elastic half-spaces, whose surfaces are loaded by constant hydrostatic pressures, is studied by using a small-deformation-superposed-on-large-deformation analysis, and the buckling condition for each case is obtained. For Blatz-Ko and harmonic compressible materials as well as Mooney incompressible material, the influence of the surface hydrostatic pressure on the critical buckling condition is discussed in detail.

Key words: semi-infinite body, finite deformation, elastic buckling, hydrostatic pressure, plane strain
