Aging of the frictional properties induced by temperature variations [PDF]
, 2010 The dry frictional contact between two solid surfaces is well-known to obey Coulomb friction laws. In particular, the static friction force resisting the relative lateral (tangential) motion of solid surfaces, initially at rest, is known to be ...

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
Advanced Functional Materials, EarlyView.A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

The influence of frictional facing thickness on the contact pressure distribution of multi-disc dry clutches [PDF]
FME Transactions, 2018 Frictional heat is generated when the clutch starts to engag. As a result of this operation the surface temperature is increased rapidly due to the difference in speed between the driving and driven parts.

On slip pulses at a sheared frictional viscoelastic/ non deformable interface
, 2000 We study the possibility for a semi-infinite block of linear viscoelastic material, in homogeneous frictional contact with a non-deformable one, to slide under shear via a periodic set of ``self-healing pulses'', i.e.

Dry friction of microstructured polymer surfaces inspired by snake skin
Beilstein Journal of Nanotechnology, 2014 The microstructure investigated in this study was inspired by the anisotropic microornamentation of scales from the ventral body side of the California King Snake (Lampropeltis getula californiae).

Admittance Selection for Planar Force-Guided Assembly for Single-Point Contact with Friction [PDF]
, 2003 This paper identifies procedures for selecting the appropriate admittance to achieve reliable planar force-guided assembly for single-point frictional contact cases. A set of conditions that are imposed on the admittance matrix is presented.

Dependence of boundary lubrication on the misfit angle between the sliding surfaces
, 2010 Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...
