- Modifying joint interfacesâ€™ contact model of two spheres makes contact model more universal. On the basis of contact theory, energy dissipation mechanism and domain expansion factorâ€™s effect, the elastoplastic fractal model of contact damping on two spheres is constructed. Numerical simulation results reveal that there is an apparent concave nonlinear relation between normal damping and load on two spheresâ€™ joint interfaces, when fractal dimension is in range of 1.2 ~ 1.4. Normal damping increases with normal load. Instead, its relation is convex nonlinear,when fractal dimension is in range of 1.6~ 1.8. It decreases with the increasing of normal load. When fractal dimension is 1.4, normal damping decreases with the increasing of fractal characteristic length parameters, when fractal dimension is 1.6, it increases with fractal characteristic length parameters.
