The use of a non-classical friction law in finite-element analysis of contact problems [PDF]
Bibliography: leaves 82-84.In this thesis a description is given of the numerical treatment of contact problems in elasticity. Frictional effects on the contact surface are modelled by using a nonlocal, nonlinear friction law.

Interaction of punches on orthotropic half-space
An integral equation of the three-dimensional contact problem for an orthotropic half-space (9 independent elastic parameters in Hooke’s law) is obtained where its kernel does not include integrals, but it depends on the solution of a characteristic ...

Biofilms and contact lenses: problems and solutions [PDF]
Contact lenses provide excellent vision correction for many people worldwide. However, they can become colonised by microorganisms and this can result in infections and inflammatory responses at the surface of the eye during wear.

Existence theorems for noncoercive incremental contact problems with Coulomb friction
For static or incremental contact problems with Coulomb friction there are satisfactory and well known existence results for the coercive case, i.e., when the elastic body is anchored so that rigid body motions are not possible, see [3, 1, 6, 7, 2].

A Note on Massively Parallel Implementation of FETI for the Solution of Contact Problems
The paper deals with the solution of large multibody contact problems using massively parallel computers and domain decomposition methods. These methods can solve the problems discretized by billions of nodal variables at the cost nearly proportional to ...

On the Efficient Reconstruction of Displacements in FETI Methods for Contact Problems
The final step in the solution of contact problems of elasticity by FETI-based domain decomposition methods is the reconstruction of displacements corresponding to the Lagrange multipliers for ''gluing'' of subdomains and non-penetration conditions.

Analysis of stick-slip phenomena using discrete element method (Examination of single-layer model)
The phenomenon called “stick-slip” is a type of self-excited vibration. When two objects slide against each other, the stick-slip phenomenon occurs.
