The Prandtl-Tomlinson model of friction with stochastic driving
(IOP Publishing, 2018-01)
We consider the classical PrandtlTomlinson model of a particle moving on a corrugated potential, pulled by a spring. In the usual situation in which pulling acts at constant velocity γ, the model displays an average friction ...
Quantum friction in two-dimensional topological materials
(American Physical Society, 2018-04)
We develop the theory of quantum friction in two-dimensional topological materials. The quantum drag force on a metallic nanoparticle moving above such systems is sensitive to the nontrivial topology of their electronic ...
A non-linear Cosserat rod model for drill-string dynamics in arbitrary borehole geometries with contact and friction
(Pergamon-Elsevier Science Ltd, 2019-07)
A model for drill-string dynamics in arbitrary borehole geometries based on the Cosserat rods theory is presented. The objective of this work is to exploit the capabilities of the Cosserat rods to capture the full range ...
Edwards Thermodynamics for a Driven Athermal System with Dry Friction
(American Physical Society, 2015-09)
We obtain, using semianalytical transfer operator techniques, the Edwards thermodynamics of a one-dimensional model of blocks connected by harmonic springs and subjected to dry friction. The theory is able to reproduce the ...
Creep motion of a model frictional system
(American Physical Society, 2011-12)
We report on the dynamics of a model frictional system submitted to minute external perturbations. The system consists of a chain of sliders connected through elastic springs that rest on an incline. By introducing cyclic ...
Electronic Friction Dominates Hydrogen Hot Atom Relaxation on Pd(100)
(American Physical Society, 2014-01)
We study the dynamics of transient hot H atoms on Pd(100) that originated from dissociative adsorption of H2. The methodology developed here, denoted AIMDEF, consists of ab initio molecular dynamics simulations that include ...
Residual stresses in similar and dissimilar friction stir welds of AA5083 and AA6061
(Trans Tech Publications, 2019-07)
Similar and dissimilar friction stir welds of AA5083 and AA6061 were produced modifying the location of the materials in the joint (advancing or retreating side) and travel speed (73 and 206 mm/min). Longitudinal and ...
A literature survey on electrical-current-assisted friction stir welding
(Multidisciplinary Digital Publishing Institute (MDPI)Switzerland, 2023)
Influence of Load, Surface Finish and Lubrication on Friction Coefficient of AISI 304 Stainless Steel
(Springer, 2020-05)
The present work aims to evaluate the friction and wear behavior of a metastable stainless steel AISI 304L against steel AISI 52100 ball. Friction tests using the “ball-on-disc” technique at constant velocity (0.03 m/s) ...
Finite strain model for contact interface in forming processes
(Wiley, 2006-12)
A phenomenological rate and state-variable friction law for the continuous sliding under lubricated and dry conditions, asit occurs in metal forming processes, is presented in this paper. The contact model is developed ...
