چکیده

Interface models coupling friction and adhesion, where adhesion is regarded as interface damage, are briefly reviewed. The most widely used cohesive zone models are presented and discussed. A general framework for these laws, recently developed by Del Piero and Raous in the form of a unified model, is outlined. As an example, it is here established that the RCCM (Raous-Cangémi-Cocou-Monerie) model is a specific case in this general framework. The variational formulation and some associated solvers are briefly recalled in the context of non smooth mechanics in the cases of both quasi-static and dynamic problems. A few examples in various fields of application are given. Lastly, some open problems and ongoing researches in this field are presented and discussed. To cite this article: M. Raous, C. R. Mécanique 333 (2010). Modles d’interface couplant adhésion et frottement Résumé On passe ici en revue de manière concise les modèles d’interface couplant frottement et adhésion, où l’adhésion est considérée comme un endommagement d’interface. Les modèles de zones cohésives les plus utilisés sont présentés et discutés. Un cadre général pour ces lois est donné sous la forme d’une formulation unifiée récemment proposée par Del Piero et Raous. Comme exemple d’application, on établit que la loi RCCM (Raous-Cangémi-Cocou-Monerie) est un cas particulier de cette formulation générale. Les formes variationnelles et quelques méthodes de résolution associées sont rappelées dans le contexte de la mécanique non régulière à la fois pour des problèmes quasi-statiques et pour des problèmes dynamiques. Quelques exemples dans des domaines d’application variés sont donnés. Enfin, quelques problèmes ouverts et des recherches en cours dans ce champ thématique sont évoqués. Pour citer cet article : M. Raous, C. R. Mécanique 333 (2010).

Model coupling friction and adhesion for steel - concrete interfaces

In this paper the interface behaviour between steel and concrete, during pull out tests, is numerically investigated using an interface model coupling adhesion and friction. This model (RCCM) was developed by Raous, Cangémi, Cocu and Monerie. It is based on the adhesion intensity variable, introduced by Frémond, which is a surface damage variable and its values vary between zero (no adhesion) a...

Biomechanics of shear-sensitive adhesion in climbing animals: peeling, pre-tension and sliding-induced changes in interface strength

Many arthropods and small vertebrates use adhesive pads for climbing. These biological adhesives have to meet conflicting demands: attachment must be strong and reliable, yet detachment should be fast and effortless. Climbing animals can rapidly and reversibly control their pads' adhesive strength by shear forces, but the mechanisms underlying this coupling have remained unclear. Here, we show ...

Rolling and Spinning Friction Characterization of Fine Particles using Lateral Force Microscopy based Contact Pushing

Here, we have utilized Lateral Force Microscopy (LFM) based mechanical pushing of micro/nano-objects to study adhesion and friction characterization at the micro/nanoscale. Continuum micro/nano-friction models for particle rolling, spinning and sliding cases are discussed for general particle-substrate interfaces. A rolling resistance model using the Double-Hertz model is devoloped for such gen...

Strong adhesion and friction coupling in hierarchical carbon nanotube arrays for dry adhesive applications.

The adhesion and friction coupling of hierarchical carbon nanotube arrays was investigated with a hierarchical multiscale modeling approach. At device level, vertically aligned carbon nanotube (VA-CNT) arrays with laterally distributed segments on top were analyzed via finite element methods to determine the macroscopic adhesion and friction force coupling. At the nanoscale, molecular dynamics ...

Sensitivity Analysis of Coulomb and HK Friction Models in 2D AFM-Based Nano-Manipulation: Sobol Method

Nanotechnology involves the ability to see and control individual atoms and molecules which are about 100 nanometer or smaller. One of the major tools used in this field is atomic force microscopy which uses a wealth of techniques to measure the topography and investigates the surface forces in nanoscale. Friction force is the representation of the surface interaction between two surfaces an...
