Comparison of contact problem exact solutions for transversely isotropic half-space

open access: yesAdvanced Engineering Research, 2015
Exact solutions to two contact problems with unknown contact domains on the elliptic punch penetration in the transversely isotropic elastic half-space are compared.

Biofilms and contact lenses: problems and solutions [PDF]

open access: yesMicrobiology Australia, 2023
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.

Contact mechanics for randomly rough surfaces [PDF]

open access: yes, 2006
When two solids are squeezed together they will in general not make atomic contact everywhere within the nominal (or apparent) contact area. This fact has huge practical implications and must be considered in many technological applications.

A Note on Massively Parallel Implementation of FETI for the Solution of Contact Problems

open access: yesAdvances in Electrical and Electronic Engineering, 2017
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

open access: yesAdvances in Electrical and Electronic Engineering, 2017
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.

Skew critical problems

open access: yes, 2007
Skew critical problems occur in continuous and discrete nonholonomic Lagrangian systems. They are analogues of constrained optimization problems, where the objective is differentiated in directions given by an apriori distribution, instead of tangent ...

Analysis of stick-slip phenomena using discrete element method (Examination of single-layer model)

open access: yesNihon Kikai Gakkai ronbunshu
The phenomenon called “stick-slip” is a type of self-excited vibration. When two objects slide against each other, the stick-slip phenomenon occurs.

On overtwisted contact surgeries

open access: yes, 2017
In this note, we obtain a new result concluding when contact (+1/n)-surgery is overtwisted. We give a counterexample to a conjecture by James Conway on overtwistedness of manifolds obtained by contact surgery. We list some problems related to the contact

Droplets move over viscoelastic substrates by surfing a ridge [PDF]

open access: yes, 2015
Liquid drops on soft solids generate strong deformations below the contact line, resulting from a balance of capillary and elastic forces. The movement of these drops may cause strong, potentially singular dissipation in the soft solid. Here we show that
