Dienstag, 10.02.2026: Mixed Finite Element Methods for Elliptic Obstacle Problems
Dr. Francisco Javier Fuica Villagra (Universidad de Santiago de Chile)
Mixed variational formulations for the first-order system of the elastic membrane obstacle problem and the second-order system of the Kirchhoff–Love plate obstacle problem are proposed. The force exerted by the rigid obstacle is included as a new unknown. A priori and a posteriori error estimates are derived for both obstacle problems. The a posteriori error estimates are based on conforming postprocessed solutions. Numerical experiments conclude this presentation.
