(last updated on 2007/04/10)Abstract:
Size dependence of average pressure for reducing thin, geometrically similar, lubricated disks of aluminum is associated with development of lubricant film breakdown at periphery; greater amount of interface sliding of larger disks led to earlier breakdown and higher stresses; however, with certain liquid lubricants size effect reversed with increasing reduction, larger disks requiring smaller stress; this is related to presence of lubricant reservoir, that increases with sample size, supplying peripheral region and controlling progress of breakdown.
