Micro/Nano Mechanics of Contact of Solids
2011Solid objects in contact with each other are omnipresent in technological applications. Due to the presence of unavoidable surface irregularities in the form of asperities, the contact is established at many locations in the form of islands, whose sizes vary from atomic scale to the size of the contacting objects.

Mechanics and Chemistry of Solids in Sliding Contact
Langmuir, 1996Wear 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 ...

Mechanisms of electriciation in solid-solid contact
1958It 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
2019AbstractThis 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

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), 1998This 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 ...

Contact Mechanics of Wearing out Solids
2007Results 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.

Reliability analysis of a mechanical contact between deformable solids
Probabilistic Engineering Mechanics, 2002Abstract 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.

Transduction Mechanism of Carbon Nanotubes in Solid-Contact Ion-Selective Electrodes
Analytical Chemistry, 2008Porous 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 (

Contact mechanics of two deformable elastic solids with graded coatings
Mechanics of Materials, 2006Abstract 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.
