Disk harmonics for analysing curved and flat self-affine rough surfaces and the topological reconstruction of open surfaces

Katrin Beyer, Guillaume Anciaux

When two bodies get into contact, only a small portion of the apparent area is actually involved in producing contact and friction forces because of the surface roughnesses. It is, therefore, crucial to accurately describe the morphology of rough surfaces, ...
