Fractal Model of Normal Contact Stiffness between Two Spheres of Joint Interfaces with Simulation

摘要

Normal contact stiffness of joint interfaces is vital to processes ranging from adhesion to friction, wear and lubrication [1, 2], It is the fact that the rough surface morphology affects the contact stiffness profoundly, and contact between surfaces is the interaction of asperities. Therefore, the interaction of asperities has been extensively studied.
