【Abstract】

<正>To predict the relief formation in stressed solid,we use a linear stability analysis that takes into account surface elasticity.The bulk material is idealized as an elastic semi-infinite continuum and the surface as a pre-stressed elastic membrane coherently bonded to the boundary of the bulk material.The total free energy of an elastic isotropic body is assumed to be the sum of the elastic strain energy and the surface energy that depends on surface deformation.
