Modeling (and) Wear Mechanisms °

In all technical fields the highest accomplishment is to formalize knowledge into mathematical (equation) format. This action serves two purposes, namely, a.To provide equations that engineers can use in product design, and,b.To add purpose and discipline to research. Overall the state of developing equations (modeling) in tribology ranges from very accomplished to primitive. Following is a list of tribology topics, covering that range, in the same order:a.Thick fluid film lubrication (hydrodynamic and elastohydrodynamic),b.Solid mechanics (elastic and plastic) of contact,c.Temperature rise in sliding surfaces,d.Surface topography,e.Frictional vibrations,f.Solid mechanics of visco-elastic contact,g.“Wear” by rolling contact fatigue,h.Wear by erosion,i.Wear by abrasion,j.Wear by sliding,k.Wear in the “boundary lubricated” state,1.Wear protection by chemical boundary film formation,m.Criteria for galling (scuffing, scoring, etc.) in lubricated sliding,n.Friction.
