      abstract     = {It has recently been suggested that many contact mechanics
                      problems between solids can be accurately studied by mapping
                      the problem on an effective one-dimensional (1D) elastic
                      foundation model. Using this 1D mapping, we calculate the
                      contact area and the average interfacial separation between
                      elastic solids with nominally flat but randomly rough
                      surfaces. We show, by comparison to exact numerical results,
                      that the 1D mapping method fails even qualitatively. We also
                      calculate the normal interfacial stiffness K and compare it
                      with the result of an analytic study. We attribute the
                      failure of the elastic foundation model to the incorrect
                      treatment of the long-range elastic coupling between the
                      asperity contact regions.},
