Web12 de mai. de 2024 · 2.2.1 Pressure and contact stiffness per unit contact area. Greenwood and Williamson once proposed a model (GW model) to study the contact between the rough surface containing Gaussian distribution asperities and the horizontal elastic plane of the same material.

Normal contact stiffness is a physical quantity related to the generalized force displacement behavior of rough surfaces in contact with a rigid body or a second similar rough surface. Rough surfaces can be seen as consisting of large numbers of asperities. As two solid bodies of the same material approach one another, the asperities interact, and they transition from conditions of non-cont…
