A Note on Duality in Reverse Convex Optimization
Joachim Gwinner
In this note we explore duality in reverse convex optimization with reverse convex inequality constraints. While we are examining the special case of a finite index set of the ineq…
On optimal control in a nonlinear interface problem described by hemivariational inequalities
Joachim Gwinner
The purpose of this paper is three-fold. Firstly we attack a nonlinear interface problem on an unbounded domain with nonmonotone set-valued transmission conditions. The investigate…
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…
Contact problems with friction for hemitropic solids: boundary variational inequality approach
A. Gachechiladze, R. Gachechiladze, J. Gwinner +1
We study the interior and exterior contact problems for hemitropic elastic solids. We treat the cases when the friction effects, described by Tresca friction (given friction model)…
An Optimization Approach to Parameter Identification in Variational Inequalities of Second Kind -- II
Joachim Gwinner
This paper continues earlier work and is concerned with the inverse problem of parameter identification in variational inequalities of the second kind that does not only treat the…
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…
Nonconvex bundle method with application to a delamination problem
M. N. Dao, J. Gwinner, D. Noll +1
Delamination is a typical failure mode of composite materials caused by weak bonding. It arises when a crack initiates and propagates under a destructive loading. Given the physica…
