A piezoelectric contact problem with slip dependent friction and damage

Kasri Abderrezak

Journal of Applied Analysis

2021

Vol. 27, nr 1

73--86

The aim of this paper is to study a quasistatic contact problem between an electro-elastic viscoplastic body with damage and an electrically conductive foundation. The contact is modelled with an electrical condition, normal compliance and the associated version of Coulomb’s law of dry friction in which slip dependent friction is included. We derive a variational formulation for the model and, under a smallness assumption, we prove the existence and uniqueness of a weak solution.

Modeling and Numerical Simulation of a Unilateral Contact Problem with Slip-dependent Friction

Vol. 37, No. 1

15-28

We construct a mathematical model which describes the contact between an elastic body and an obstacle, the so-called foundation. The contact is frictional and is modelled with normal compliance and unilateral constraint, associated to a slip- dependent version of Coulomb’s law of dry friction. We present a detailed description Of the model, then we provide numerical simulations in the study of a two-dimensional Example. Our aim is to underline the influence of the parameters involved in the boundary conditions, which could give rise to different status of the material points c>n the contact surface.

Dynamic Contact Problems With Slip-Dependent Friction in Viscoelasticity

Ionescu I. R., Nguyen Q. L.

International Journal of Applied Mathematics and Computer Science

2002

Vol. 12, no 1

71-80

The dynamic evolution with frictional contact of a viscoelastic body is considered. The assumptions on the functions used in modelling the contact are broad enough to include both the normal compliance and the Tresca models. The friction law uses a friction coefficient which is a non-monotone function of the slip. The existence and uniqueness of the solution are proved in the general three-dimensional case.
