Influence of MHD Lubrication and Textured Surface in EHL Line Contact
Frontiers in Mechanical Engineering, 2019 The present numerical study investigates the combined effect of micro-texture and magneto hydrodynamic lubrication behavior on the performance of elastohydrodynamic lubrication (EHL) line contact.

A miniature non-circular line gear with pure-rolling contact
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 The design of pure-rolling gear has always been a subject of intense research, because in some working conditions, such as dry friction, pure-rolling gear has higher transmission efficiency and less possibility of transmission failure. Non-circular gears

Is contact-line mobility a material parameter?
npj Microgravity, 2022 Dynamic wetting phenomena are typically described by a constitutive law relating the dynamic contact angle θ to contact-line velocity U C L . The so-called Davis–Hocking model is noteworthy for its simplicity and relates θ to U C L through a contact-line

Critical Dynamics of Contact Line Depinning [PDF]
MRS Proceedings, 1994 ABSTRACTThe depinning of a contact line is studied as a dynamical critical phenomenon by a functional renormalization group technique. In D = 2 - ∈ “line” dimensions, the roughness exponent is ζ = ∈/3 to all orders in perturbation theory. Thus, ζ = 1/3 for the contact line, equal to the Imry-Ma estimate for equilibrium roughness. The dynamical exponent

A Finite Element Approach for the Line-to-Line Contact Interaction of Thin Beams with Arbitrary Orientation [PDF]
arXiv.org, 2016 The objective of this work is the development of a novel finite element formulation describing the contact interaction of slender beams in complex 3D configurations involving arbitrary beam-to-beam orientations.
