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… WebThe default values can be computed according to (after some simplifications of the expressions in Plaxis manual): Tangential stiffness : Ks = G / t × ( Rinter) 2, Normal stiffness : Kn =11× Kt ... cullman dodge chrysler jeep ramWebSo there is actually a separate normal and tangential contact stiffness.
