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 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 =...
