Abstract: A model for the steady-state wear behavior of polymer composite materials, including the effects of preferential load support by and surface accumulation of wear-resistant filler particles, is ...

Abstract: The load applied to a lead screw assembly is distributed amongst the engaged threads of its wearing nut in a manner that can range from highly nonuniform to nearly uniform. Nonuniform load ...

Abstract: The in situ vapor-phase lubrication of M50 steel, in combined rolling and sliding contacts at 540°C using nitrogen atmospheres containing acetylene, is achieved. Acetylene partial pressures ...

Abstract: A time-dependent description of the sliding wear behavior of hard particle-filled polymer composites is developed. The description is based upon the accumulation of wear-resistant filler particles ...

Abstract: A simulation has been developed to model the transient wear of particle-filled polymer composites as a function of sliding distance. All inputs are parameters of physical significance, including ...

Abstract: This study investigates fluid absorption behavior of an unirradiated and a heavily crosslinked ultra-high molecular weight polyethylene (UHMWPE) exposed to bovine serum with pressures varying from ...
