The nonlinear normal vibration of a block of rough surface in visco-elastic interaction with a rough plane is considered. The nonlinear normal free vibration response corresponds to the application of a constant compressive external load, thereby establishing an equivalent contact stiffness for the system. Closed-form equations relating contact damping ratio and contact natural frequency to the surface parameters are given.
