Contact - Friction of Fuzzy Type. Contact - Friction of Fractal Type
1995The aim of this paper is to introduce fuzzy and fractal friction laws. Fuzzy superpotential laws were first considered by the second author in Panagiotopoulos (1993). The phenomenon is described in terms of a nonconvex superpotential which is appropriately defined and a hemivariational inequality is obtained.

In metalworking processes the workpiece is deformed by the contact with the die. The pressure required for deformation generates a stress normal to the die surface. The movement of the workpiece relative to the die surface generates a shear stress at the interface.

Friction under elastic contacts
Surface and Coatings Technology, 2000The friction coefficients and shear stresses for a sliding contact at low loads are calculated on the basis of the elastic contact and adhesion beneath a sliding spherical indenter and compared to experimental data. The contribution of the adhesion appeared to be negligible.

Contact Problems with Friction
2016Contact problems become much more complicated when a kind of friction is taken into account, even in the case that we restrict our attention to 3D problems of linear elasticity. The problems start with the formulation of friction laws, which are of phenomenological nature.

Frictional Contact-impact Problems
1993Abstract In Chapters 4 and 5, tangential contact forces between two contacting boundaries were not considered, i.e. frictional effects were neglected. In reality, however, friction phenomena exist wherever contacts occur. In many engineering applications, the effects of friction may play very important roles.

This chapter introduces contact forces and pressures and its modelling; consequent to this is friction as occurs within the structure and between the constituent components. Various friction or more correctly energy dissipative mechanisms are identified and are grouped into two categories; those that arise because of relative motion between components ...

Contact Problems Involving Friction
2019The Coulomb friction law is simple to apply in the formulation of elastic contact problems, but it is also a rich source of unexpected physical phenomena, including ranges of unstable dynamic response, history-dependence, ‘wedging’ and mathematical problems of existence and uniqueness of solution.

Contact, friction and propulsion
2003A knowledge of Newtonian mechanics is an essential historical and pedagogical foundation for physical theory, but it is also a source of considerable difficulty. It is typically the arena where common sense ideas and reasoning clash with the theory taught1. Not that it is difficult to state or remember the basic law of dynamics for a particle, (F=ma in
