      abstract     = {A press fit, also known as interference fit or friction
                      fit, is a form of fastening between two tight fitting mating
                      parts (usually two bodies with cylinder or conical surfaces)
                      that produces a joint which is held together by friction
                      after the parts are pushed together. I discuss the influence
                      of surface roughness on the design of press fits. This topic
                      has been addressed in the engineering community but only on
                      an empirical level without a scientific backup. Here, I will
                      apply the Persson contact mechanics theory to show how to
                      include the surface roughness in the design criteria. I
                      argue that one should use what I denote as the cylinder
                      “stylus width” rather than the “caliper width” when
                      determining the influence of the surface roughness of the
                      compression (also denoted as the interference). In the
                      classical approach using the caliper width, the compression
                      is assumed to be independent of the elastic properties of
                      the solids, but in the more accurate approach presented here
                      using the stylus width the compression depends on the
                      elastic properties and on the surface roughness power
                      spectra of the involved solids. A detailed discussion of the
                      relation between the root-mean-square roughness amplitude
                      hrms and the maximum asperity height hmax, of interest in
                      its own right, is also presented as it is needed for
                      determining the relation between the stylus and caliper
                      derived compression’s.},
