Experimental Verification of the Boundary Element Method for Adhesive Contacts of a Coated Elastic Half-Space

Lubricants, 2023
We consider analytical, numerical, and experimental approaches developed to describe the mechanical contact between a rigid indenter and an elastic half-space coated with an elastic layer.

Microscale friction reduction by normal force modulation in MEMS. [PDF]

, 2010
Friction in MEMS-scale devices is troublesome because it can result in lateral stiction of two sliding surfaces. We have investigated the effect of modulation of the normal force on the friction between two sliding MEMS surfaces, using a fully MEMS-based

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

Microstructure and mechanical properties of refill friction stir spot welded joints: Effects of tool size and welding parameters

Journal of Materials Research and Technology, 2022
A novel refill friction stir spot welding (RFSSW) technique employing large-sized tools is proposed. The microstructure and mechanical properties of joints produced with a large-sized welding tool and a conventional tool are compared.

Topological complexity of frictional interfaces: friction networks [PDF]

Nonlinear Processes in Geophysics, 2012
Abstract. Through research conducted in this study, a network approach to the correlation patterns of void spaces in rough fractures (crack type II) was developed. We characterized friction networks with several networks characteristics. The correlation among network properties with the fracture permeability is the result of friction networks.

Frictional Effects in Biomimetic Scales Engagement

, 2015
Scales engagement can contribute significantly to nonlinear bending behavior of elastic substrates with rigid biomimetic scales. In this letter, we investigate the role of friction in modulating the nonlinearity that arises due to self-contact of scales ...

Nanofriction mechanisms derived from the dependence of friction on load and sliding velocity from air to UHV on hydrophilic silicon [PDF]

, 2005
This paper examines friction as a function of the sliding velocity and applied normal load from air to UHV in a scanning force microscope (SFM) experiment in which a sharp silicon tip slides against a flat Si(100) sample.
