Contact stiffness of steel
WebWhen bodies come into contact, there is a normal force and a shear force (unless it’s a frictionless interface). So there is actually a separate normal and tangential contact stiffness. Too low a tangential stiffness could … WebUnderstanding the definition of stiffness. Knowledge of the mechanical properties of materials. The material’s tensile modulus.
