RISNon-Newtonian Lubrication With the Second-Order Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In certain applications where the lubricant is subjected to rapidly changing conditions along its flowing path (such as an elastohydrodynamic contact), the inherently time dependent nature of the ...
The Evolution of Geometry for a Wearing Circular Cam: Analytical and Computer Simulation With Comparison to Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The evolution of the geometry of a simple two-dimensional circular cam as a result of wear is studied using three complementary approaches: a closed form analytical expression, a computer ...
Fractional Coverage Model for the Adsorption and Removal of Gas Species and Application to Superlow Friction Diamond-Like Carbon
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The frictional behavior of diamond-like carbon (DLC) films varies with environmental condition. One theory asserts that the cause of variations in the frictional performance is environmental ...
Quantifying Multidirectional Sliding Motions in Total Knee Replacements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This manuscript describes a formulaic method to predict the severity of crossing motions experienced by ultra-high-molecular-weight polyethylene (UHMWPE) under sliding conditions across a bearing ...
A Gas-Surface Interaction Model for Spatial and Time-Dependent Friction Coefficient in Reciprocating Contacts: Applications to Near-Frictionless Carbon
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closed-form time- and position-dependent model for coverage, based on the adsorption of environmental contaminants and their removal through the pin contact, is developed for reciprocating ...
