Coupling of finite element and boundary element methods with regularization for a nonlinear interface problem with nonmonotone set-valued transmission conditions
J. Gwinner, N. Ovcharova
For the first time, a nonlinear interface problem on an unbounded domain with nonmonotone set-valued transmission conditions is analyzed. The investigated problem involves a nonlin…
On the use of elliptic regularity theory for the numerical solution of variational problems
A. Dreves, J. Gwinner, N. Ovcharova
In this article we show the crucial role of elliptic regularity theory for the development of efficient numerical methods for the solution of some variational problems. Here we foc…
Improved stabilization technique for frictional contact problems solved with hp-BEM
Lothar Banz, Gregor Milicic, Nina Ovcharova
We improve the residual based stabilization technique for Signorini contact problems with Tresca friction in linear elasticity solved with -mixed BEM which has been recently an…
On the coupling of regularization techniques and the boundary element method for a hemivariational inequality modelling a delamination problem
N. Ovcharova
In this paper, we couple regularization techniques of nondifferentiable optimization with the h-version of the boundary element method (h-BEM) to solve nonsmooth variational proble…
Semicoercive Variational Inequalities - From Existence to Numerical Solution of Nonmonotone Contact Problems
Nina Ovcharova, Joachim Gwinner
In this paper we present a novel numerical solution procedure for semicoercive hemivariational inequalities. As a model example we consider a unilateral semicoercive contact proble…
