Adhesive and molecular friction in tribological conjunctions [PDF]
, 2012 This thesis investigates the underlying causes of friction and ine ciency within an internal combustion engine, focusing on the ring-liner conjunction in the vicinity of the power-stroke top dead centre reversal.

Static Strength of Friction-Type High-Strength Bolted T-Stub Connections under Shear and Compression
Applied Sciences, 2020 The friction-type high-strength bolted (FHSB) T-stub connection has been widely used in steel structures, due to their good fatigue resistance and ease of installation.

Influence of micro asperity-valley on the surface of forging tools on tribological conditions [PDF]
Computer Methods in Materials Science, 2007 The relationship between apparent coefficient of friction, surface roughness and the yield stress of solid lubricant is examined using rigid-plastic finite element analysis. The minimum lubricant thickness decreases significantly when σYL/p < 1/10, where

Experimental discrimination of plowing friction and shear friction
Tribology Letters, 2006 The friction experienced by a hard indenter plowing through a relatively soft material consists of two contributions. The plastic deformation of the soft specimen yields a plowing friction component while the shear forces at the area of contact yield shear friction [1–3].

A new material model for 2D numerical simulation of serrated chip formation when machining titanium alloy Ti-6Al-4V [PDF]
, 2008 A new material constitutive law is implemented in a 2D finite element model to analyse the chip formation and shear localisation when machining titanium alloys. The numerical simulations use a commercial finite element software (FORGE 2005) able to solve

On the shear thinning of non-Brownian suspensions: Friction or adhesion?
Journal of Non-Newtonian Fluid Mechanics, 2020 Shear thinning is fundamental to a broad range of particle suspensions, both in nature and in industrial applications. Yet the mechanisms governing it remain unclear.

Friction and Shear Strength at the Nanowire–Substrate Interfaces [PDF]
Nanoscale Research Letters, 2009 Abstract The friction and shear strength of nanowire (NW)–substrate interfaces critically influences the electrical/mechanical performance and life time of NW-based nanodevices. Yet, very few reports on this subject are available in the literature because of the experimental challenges involved and, more specifically no studies have been ...
