Abstract
I study the contact between a rigid solid with a randomly rough surface and an elastic block with a flat surface. I derive a relation between the (average) interfacial separation and the applied normal squeezing pressure . I show that, for nonadhesive interaction and small applied pressure, , in good agreement with recent experimental observations.
