A first order friction model for lubricated sheet metal forming
Theoretical and Applied Mechanics Letters, 2018 : This paper presents the derivation of a first order friction model for lubricated sheet metal forming. Assuming purely plastic real contacts, Newton's law of viscosity, and a square root behavior of the hydrodynamic coefficient of friction with respect

Finite element modelling and experimental study of oblique soccer ball bounce [PDF]
, 2011 In this study, we develop a finite element model to examine the oblique soccer ball bounce. A careful simulation of the interaction between the ball membrane and air pressure in the ball makes the model more realistic than analytical models, and helps us

The wheel-rail contact friction influence on high speed vehicle model stability [PDF]
Transport Problems, 2015 Right estimating of the coefficient of friction between the wheel and rail is essential in modelling rail vehicle dynamics. Constant value of coefficient of friction is the typical assumption in theoretical studies.

Nanofriction behavior of cluster-assembled carbon films [PDF]
, 2002 We have characterized the frictional properties of nanostructured (ns) carbon films grown by Supersonic Cluster Beam Deposition (SCBD) via an Atomic Force-Friction Force Microscope (AFM-FFM). The experimental data are discussed on the basis of a modified
