A Convergence Criterion for Elliptic Variational Inequalities
Claudia Gariboldi, Anna Ochal, Mircea Sofonea +1
We consider an elliptic variational inequality with unilateral constraints in a Hilbert space which, under appropriate assumptions on the data, has a unique solution . We fo…

Modelling, Analysis and Numerical Simulation of a Spring-Rods System with Unilateral Constraints
Anna Ochal, Wiktor Prządka, Mircea Sofonea +1
In this paper we consider a mathematical model which describes the equilibrium of two elastic rods attached to a nonlinear spring. We derive the variational formulation of the mode…

Duality Arguments in the Analysis of a Viscoelastic Contact Problem
Piotr Bartman, Anna Ochal, Mircea Sofonea
We consider a mathematical model which describes the quasistatic frictionless contact of a viscoelastic body with a rigid-plastic foundation. We describe the mechanical assumptions…
