HYBRID FINITE ELEMENT FOR THE ANALYSIS ON NON-MATCHED MESHES

Abstract

A variational approach for «glueing» of non-matched interfaces is proposed. Lagrange's multipliers introduced on a general functional level are explicitly defined by the basic independent variables. Thereby the global system of equations includes only nodal degrees of freedom. The formulation is verified by the standard and contact patch-tests.

Keywords: non-matched mesh, Reissner's functional, Lagrange's multipliers, hybrid finite element.
