Contact stiffness of steel
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… WebMar 20, 2024 · Add a comment. 1. Young's modulus E = tensile stress tensile strain = ( F A) ( l L) ⇒ F = E A L l ⇒ Δ F = E A L Δ l. This gives the spring constant k = Δ F Δ A = E A L. …
