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…
Vectorized 3D mesh refinement and implementation of primal hybrid FEM in MATLAB
Harish Nagula Mallesham, Sharat Gaddam, Jan Valdman +1
In this article, we introduce a Face-to-Tetrahedron connectivity in MATLAB together with a vectorized 3D uniform mesh refinement technique. We introduce a MATLAB vectorized assembl…
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…
Bubbles Enriched Quadratic Finite Element Method for the 3D-Elliptic Obstacle Problem
Sharat Gaddam, Thirupathi Gudi
Optimally convergent (with respect to the regularity) quadratic finite element method for two dimensional obstacle problem on simplicial meshes is studied in (Brezzi, Hager, Raviar…
Inhomogeneous Dirichlet Boundary Condition in the A Posteriori Error Control of the Obstacle Problem
Sharat Gaddam, Thirupathi Gudi
We propose a new and simpler residual based a posteriori error estimator for finite element approximation of the elliptic obstacle problem. The results in the article are two fold.…
