title: Upon wear mechanism and breakdown susceptibility of equipment operating under conditions of impact and vibrational loads
abstract: Wear of nominally fixed joints of machine parts, being in contact through dry friction and operating under conditions of impact loads, is considered. The machines in question are exemplified by screens, crushers, mills; while the joints in question are exemplified by flanged connections, bolt &ndash; nut connections, etc. This kind of wear is of paradoxical character: at first glance, it should not occur. The paper considers two directly contrary mechanical models of this kind of wear, that may
