### Rough sphere

Antoine Sanner & Lars Pastewka
Example illustrating the contact of a rough sphere that behaves as a nominally flat rough surface at small normal forces while it follows the Hertzian theory of smooth spheres at large normal forces. This dataset is similar to the simulations in https://doi.org/10.1063/1.4950802 The topographies were generated with the following Python code: ` from SurfaceTopography.Generation import fourier_synthesis from SurfaceTopography.Special import make_sphere import numpy as np a0 = 1 # Pixel size radius = 10000 n =...
