Composites. Part A, Applied science and manufacturing, 2020
A custom-built test device was developed to measure the inter-ply shear resistance of dry carbon woven fabrics as well as prepregs at different temperatures, consolidation pressures, and forming rates typical to those used in autoclave processing.

Proceedings of the Institution of Mechanical Engineers, 1972
The phenomena observed when a lubricated contact or bearing is operating under mixed lubrication conditions are assumed to arise from an interaction of the surface asperities or roughness as well as from hydro-dynamic action of the sliding surfaces. It is shown how one of the previously published stochastic models of hydrodynamic lubrication can be ...

Lubrication Science, 2020
In this paper, the angular contact ball bearings under low‐speed and heavy‐load conditions is studied with a coupled numerical method of mixed elastohydrodynamic lubrication (EHL) and quasi‐dynamic analysis.

Chemical Films and Mixed Lubrication
A S L E Transactions, 1983This paper relates studies of film behavior in mixed lubrication in a concentrated contact. In the simulator, 52100 steel specimens and TCP in hexadecane as lubricant are used. When the pure EHL regime is studied, no solid film is formed on surfaces, but within the boundary lubrication regime, the chemical decomposition of the additive contributes to a

A mixed lubrication analysis of a thrust bearing with fractal rough surfaces
Proceedings of the Institution of mechanical engineers. Part J, journal of engineering tribology, 2020Fractal descriptions of rough surfaces are widely used in tribology. The fractal dimension, D, is an important parameter which has been regarded as instrument and scale independent, although recent findings bring this into question.

Reduced description of mixed lubrication
Tribology International, 2008Modelling friction and wear between rough and lubricated surfaces is an important problem of modern technologies. The complexity of the problem is in the necessity of simultaneously solving for elastic deformations of contacting bodies and fluid flow between the bodies.

Dynamic Adsorption in Mixed Lubrication
Tribology Transactions, 1989The effect of additive adsorption on friction and wear of sliding contacts under mixed lubrication conditions has been analysed. Dynamic aspects of adsorption are taken into account by relating desorption in the contact zone to increased temperature rather than to some mechanical action.

Mixed rheologies in elastohydrodynamic lubrication
Industrial Lubrication and Tribology, 2004This paper studies elastohydrodynamic lubrication (EHL) of line contacts for the slide‐roll ratios 0‐2 based on the assumptions of interfacial shear strength and interfacial slip. It is shown that the viscoelastic, viscoplastic and non‐continuum fluids distribute from the inlet zone to the Hertzian contact zone in order for a given operating condition ...

Effect of Liquid-Solid Lubricant on Mixed Lubrication in Line Contact
Applied Mechanics and Materials, 2011This paper presents the performance characteristics of two surfaces in line contact under isothermal mixed lubrication with non-Newtonian liquid–solid lubricant base on Power law viscosity model. The time dependent Reynolds equation, elastic equation and viscosity equation were formulated for compressible fluid.
