A Quadratic Interior Penalty Method for the von Kármán Obstacle Problem
Sharat Gaddam
This article proposes and analyses a quadratic interior penalty method for the displacement obstacle problem of the von Kármán plate. The discrete space consists of Lagrange…

Morley Finite Element Method for the von Kármán Obstacle Problem
Carsten Carstensen, Sharat Gaddam, Neela Nataraj +2
This paper focusses on the von Kármán equations for the moderately large deformation of a very thin plate with the convex obstacle constraint leading to a coupled system of semilin…
