Numerical Analysis of a Quasistatic Problem of Sliding Frictional Contact with Wear
We consider numerical approximations of a quasistatic problem modeling the sliding frictional contact with wear between a viscoelastic body and a rigid moving foundation. The contact is modeled with the Coulomb's law of dry friction and the wear is described by a version of Archard's law. The variational formulation of the problem consists of a nonlinear evolutionary equation coupled with a tim...
متن کاملNumerical Analysis of a Contact Problem in Rate-Type Viscoplasticity
In this paper, we consider numerical approximations of a contact problem in rate-type viscoplasticity. The contact conditions are described in term of a subdiierential and include as special cases some classical frictionless boundary conditions. The contact problem consists of an evolution equation coupled with a time-dependent variational inequality. Error estimates for both spatially semi-dis...
متن کاملNumerical Analysis of a Transmission Problem with Signorini Contact Using Mixed-fem and Bem
This paper is concerned with the dual formulation of the interface problem consisting of a linear partial differential equation with variable coefficients in some bounded Lipschitz domain Ω in R n (n ≥ 2) and the Laplace equation with some radiation condition in the unbounded exterior domain Ωc := R n\Ω̄. The two problems are coupled by transmission and Signorini contact conditions on the interf...
متن کاملNumerical Approximation of a Singularly Perturbed Contact Problem
As a simpliied model for contact problems, we study a mixed Neumann-Robin boundary value problem for the Laplace operator in a smooth domain in R 2. The Robin condition contains a small parameter " inducing boundary layers of corner type at the transition points as proved in 4]. We present an integral equation for the numerical solution of this problem together with estimates of the error. We i...
متن کاملVariational and Numerical Analysis of the Signorini’s Contact Problem in Viscoplasticity with Damage
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. We provide a variational formulation for the mechanical problem and sketch a proof of the existence of a uniqueweak solutio...
