Wear on mechanical contacts - Issues and definitions

At the macroscopic level, this is what happens, for example, in the case of misalignment of a shaft in its bearing, when the shaft "makes room" for itself on the edge of the bearing. If the accommodation properties were not sufficient in such a case, the abnormally high contact pressure could lead to surface damage (cracking, decohesion, etc.) due to edge overpressure (figure 1 ). Accommodation, which may concern surfaces at the...
