Contact Mechanics and Surface Roughness
This is our first online lecture on contact mechanics and rubber friction. It comprehends a short introduction to contact mechanics and then focuses on understanding surface roughness. Because all surfaces in Nature and technology are rough, it is necessary to mathematically model and describe surface roughness. Please also check out the auxilary material where we explain how surface roughness can be modeled using sinusoidal waves.

Fourier Transformation of Surface Roughness
Here we show some auxilary material to our first online lecture on surface roughness. This lecture illustrates the Fourier transform of a measured roughness profile using sinusoidal waves. This is of great importance if you want to understand how the Power Spectrum of randomly rough surfaces can be calculated.
