Abstract
Nonlinear dynamic models for frictional interfaces require a number of input parameters to allow a realistic representation of the contact interface. Interface geometry and static pressure distributions can be obtained reliably from numerical analysis. However, it is also necessary to measure the friction coefficient, and the tangential and normal contact stiffness. The tangential contact stiffness plays a significant role in the dynamic response, but is very challenging to measure. In this paper quasi-static and dynamic experiments developed at the University of Oxford and at Imperial College London respectively, will be compared and discussed. Of particular interest is the dependence of the stiffness on the static normal load and the overall contact area.
