Finite-element analysis of contact between elastic self-affine surfaces
Finite-element analysis of contact between elastic self-affine surfaces
Finite-element methods are used to study nonadhesive, frictionless contact between elastic solids with self-affine surfaces. We find that the total contact area rises linearly with the load at small loads. The mean pressure in the contact regions is independent of load and proportional to the root-mean-square slope of the surface. …
