Numerical analysis of a non-clamped dynamic thermoviscoelastic contact problem

open access: yes, 2019
In this work we analyze a non-clamped dynamic viscoelastic contact problem involving thermal effect. The friction law is described by a nonmonotone relation between the tangential stress and the tangential velocity.

A dynamic Tresca’s frictional contact problem with damage for thermo elastic-viscoplastic bodies [PDF]

open access: yes, 2019
We consider a dynamic contact problem between an elastic-viscoplastic body and a rigid obstacle. The contact is frictional and bilateral, the friction is modeled with Tresca’s law with heat exchange.

Global existence for a nonlocal model for adhesive contact

open access: yes, 2017
In this paper we address the analytical investigation of a model for adhesive contact, which includes nonlocal sources of damage on the contact surface, such as the elongation.

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

open access: yesDemonstratio 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 ...

Optimal control of an Allen-Cahn equation with singular potentials and dynamic boundary condition

open access: yes, 2014
In this paper, we investigate optimal control problems for Allen-Cahn equations with singular nonlinearities and a dynamic boundary condition involving singular nonlinearities and the Laplace-Beltrami operator.

Extensions of the control variational method [PDF]

open access: yes, 2010
The control variational method is a development of the variational approach, based on optimal control theory. In this work, we give an application to a variational inequality arising in mechanics and involving unilateral conditions both in the domain and

A comparison of delamination models: Modeling, properties, and applications [PDF]

open access: yes, 2017
This contribution presents recent results in the modeling and the analysis of delamination problems. It addresses adhesive contact, brittle, and cohesive zone models both in a quasistatic and a viscous, dynamic setting for the bulk part.

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

open access: yesDemonstratio 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.

Thermodynamics and analysis of rate-independent adhesive contact at small strains

open access: yes, 2010
We address a model for adhesive unilateral frictionless Signorini-type contact between bodies of heat-conductive viscoelastic material, in the linear Kelvin-Voigt rheology, undergoing thermal expansion.
