Influence of Feed Motion on Surface Friction of AISI 1045 Steel Machined by a Fine-Grinding Process
Tribology in Industry, 2021 Fine-grinding is a final machining method used to reach the low friction and high-quality surface. The workspeed (vw) and crossfeed (vc) motions are perpendicular to each other and differ in value during the grinding process. Thus, the surface quality in

Effect of the Friction Coefficient on Clinch Joints
International journal of engineering, management and sciences, 2020 In this study the effect of the friction coefficient on the clinch joints was examined in experimental and numerical way also. The knowledge of the frictional behaviour during the mechanical joining (i.e. clinching) is important from the point of view of

The dependence of the dry friction threshold on rupture dynamics
, 2011 The static friction coefficient between two materials is considered to be a material constant. We present experiments demonstrating that the ratio of shear to normal force needed to move contacting blocks can, instead, vary systematically with ...

Static friction coefficient depends on the external pressure and block shape due to precursor slip
Scientific Reports, 2023 Amontons’ law states that the maximum static friction force on a solid object is proportional to the loading force and is independent of the apparent contact area.

Active Microrheology of Driven Granular Particles
, 2013 When pulling a particle in a driven granular fluid with constant force $F_{ex}$, the probe particle approaches a steady-state average velocity $v$. This velocity and the corresponding friction coefficient of the probe $\zeta=F_{ex}/v$ are obtained within

Effect of pulsed magnetic field pre-treatment of AISI 52100 steel on the coefficient of sliding friction and wear in pin-on-disk tests [PDF]
, 2014 Disc specimens manufactured from commercial bearing rollers (AISI 52100 steel, 62–63 HRC) in initial state and after pre-treatment by pulsed magnetic field (PMF) with a magnetic field strength of 1–7 MA/m were tested with sunflower oil using pin-on-disk ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
