Convergence Results for Elliptic Variational-Hemivariational Inequalities

Advances in Nonlinear Analysis, 2020
We consider an elliptic variational-hemivariational inequality 𝓟 in a reflexive Banach space, governed by a set of constraints K, a nonlinear operator A, and an element f.

Variational and numerical analysis of the Signorini′s contact problem in viscoplasticity with damage

Journal of Applied Mathematics, Volume 2003, Issue 2, Page 87-114, 2003., 2003
We consider the quasistatic Signorini′s contact problem with damage for elastic‐viscoplastic bodies. The mechanical damage of the material, caused by excessive stress or strain, is described by a damage function whose evolution is modeled by an inclusion of parabolic type.

On the frictionless unilateral contact of two viscoelastic bodies

Journal of Applied Mathematics, Volume 2003, Issue 11, Page 575-603, 2003., 2003
We consider a mathematical model which describes the quasistatic contact between two deformable bodies. The bodies are assumed to have a viscoelastic behavior that we model with Kelvin‐Voigt constitutive law. The contact is frictionless and is modeled with the classical Signorini condition with zero‐gap function.

A frictionless contact problem for viscoelastic materials

Journal of Applied Mathematics, Volume 2, Issue 1, Page 1-21, 2002., 2002
We consider a mathematical model which describes the contact between a deformable body and an obstacle, the so‐called foundation. The body is assumed to have a viscoelastic behavior that we model with the Kelvin‐Voigt constitutive law. The contact is frictionless and is modeled with the well‐known Signorini condition in a form with a zero gap function.

Penalty method for unilateral contact problem with Coulomb's friction in time-fractional derivatives

Demonstratio Mathematica
The purpose of this work is to study a mathematical model that describes a contact between a deformable body and a rigid foundation. A linear viscoelastic Kelvin-Voigt constitutive law with time-fractional derivatives describes the material’s behavior ...

A Rothe method for a viscoelastic contact problem involving time-fractional derivatives in locking materials

Demonstratio Mathematica
This study examines a contact problem involving viscoelastic materials interacting with a rigid foundation. The constitutive relationship is derived from a time-fractional Kelvin–Voigt model.
