Particle Deformation and Counterface Damage When Relatively Soft Particles are Squashed Between Hard Anvils

Abstract
Results from particle squashing tests designed to simulate the process of rolled in lubricant debris in rolling element bearings, are presented and showed to compare well with an earlier published theory. Measurements of the harder anvils after squashing various hard particles confirm our earlier theoretical results, that even very soft debris materials can cause plastic deformation in the hard counterfaces.
