Elastically mediated interactions between surface domains are classically described in terms of point forces. Such point forces leadto local strain divergences that are usually avoided by introducing a poorly defined cut-off length. In this work, we develop a self-consistent approach in which the strain field induced by the surface domains is expressed as the solution of an integral equation thatcontains surface elastic constants, Sij . For surfaces with positive Sij the new approach avoids the introduction of a cut-off length.The classical and the new approaches are compared in case of 1-D periodic ribbons.
