Mechanics and Chemistry of Solids in Sliding Contact

Langmuir, 1996
Wear behavior of coated surfaces has been studied extensively over the past 20 years. Although the behavior can be discussed in terms of classical models, it is described more completely using third-body concepts. These concepts consider the processes that take place at a moving interface : deformation and particle detachment, third-body formation and ...

Reliability analysis of a mechanical contact between deformable solids

Probabilistic Engineering Mechanics, 2002
Abstract The contact problems in mechanics are very complex. The behavior of a structure, where a contact occurs, depends on some assumptions on the design parameters and is in general highly nonlinear. Several deterministic numerical methods have been developed on finite element codes and give accurate solutions of contact problems.

Mechanisms of electriciation in solid-solid contact

1958
It is precisely in this area that the greatest confusion exists. Aside from the complications produced by the action of films of moisture, electrolytic effects and/or the formation of electrolytic Helmholtz double layers, or by films of impurity, phenomena are complicated by other factors.

Mechanical Properties of Solids and Real Area of Contact

2019
AbstractThis chapter covers how the material around contacting asperities deforms when two surfaces touch and the resulting stresses in the materials. The beginning portion of the chapter is devoted to how these stresses and deformations originate at the atomic level. Next, discussed are the elastic and plastic deformations that can occur when a single

Contact Mechanics of Wearing out Solids

2007
Results of abrasive wear are identified as irreversible changes in bodies contours and as an increase of a clearance gap between contacting solids. Loose wear particles detached from the bodies transmit loads and displacements at the contact interface.

Transduction Mechanism of Carbon Nanotubes in Solid-Contact Ion-Selective Electrodes

Analytical Chemistry, 2008
Porous carbon materials and carbon nanotubes were recently used as solid contacts in ion-selective electrodes (ISE), and the signal transduction mechanism of these carbon-based materials is therefore of great interest. In this work the ion-to-electron transduction mechanism of carbon nanotubes is studied by using electrochemical impedance spectroscopy (

Assessment of Techniques for Contact-Pair Detection in Solid Mechanics

Anais do X Simpósio Brasileiro de Arquitetura de Computadores e Processamento de Alto Desempenho (SBAC-PAD 1998), 1998
This work presents some basic concepts of a technique used for modeling contact-impact problems between deformable solids through penalized finite element formulation handling the impenetrability condition and conserving momentum. This technique uses the concept of discrete particles and provides a way to treat general contact configurations due an ...

Numerical Study of Solid Oxide Fuel Cell Contacting Mechanics

Fuel Cells, 2018
AbstractAssembly of a planar solid oxide fuel cell (SOFC) or solid electrolyzer (SOE) stack involves the lamination of cells and interconnect plates under an applied load. In most designs a pattern of ribs on the interconnector makes contact with a porous ceramic current collector layer on the air side. These localized contacts are regions of increased

Contact mechanics of two deformable elastic solids with graded coatings

Mechanics of Materials, 2006
Abstract The contact problem for two deformable solids with FGM coatings is considered. The problem is considered under the assumption of plane strain, Coulomb friction and linear nonhomogeneous elasticity. The variation of the elastic modulus in the FGM coatings are exponential.
