Tribological Response of Glass Fiber/Polyester Composites After Pressurized Water-Immersion Aging Assessed by Reciprocating and Ball-on-Disc Wear Testing [PDF]
PolymersThis study quantifies how pressurized water-immersion aging degrades the tribological response of cross-ply E-glass/polyester laminates by coupling dual-mode testing with surface metrology and factorial ANOVA. Eleven-ply [0/90]s plates were aged at 10 bar for 0, 7, 14, and 21 days, gaining 10% mass (72.2 to 79.4 g), then tested under 20 N in ball-on ...

Friction in Metal-on-Metal Total Disc Arthroplasty: Effect of Ball Radius [PDF]
Journal of Biomechanics, 2012 Total Disc Arthroplasty (TDA) can be used to replace a degenerated intervertebral disc in the spine. There are different designs of prosthetic discs, but one of the most common is a ball-and-socket combination.
