Lire la suite >Frictional interaction of two elastic spheres is a fundamental problem of contact mechanics. The tangential displacement depends on the normal and tangential force in a complicated and, in general, hysteretic way. The key characteristic of the system is the traction distribution in the contact zone that has a complex piecewise-smooth character. We propose a method of memory diagrams that enables to extract all memory information from traction distributions and store it in a compact manner. Then, instead on considerations on the case-to-case basis of a particular loading history, a general algorithm applicable for any loading history can be formulated. Finally, we used the obtained solution to prove that friction of two spheres is the Preisach system. The Preisach formulation of the problem enables to replace the custom-made algorithm of the memory diagrams method by a standard routine used over more than 70 years in ferromagnetismLire moins >
