Abstract

The error estimation by pure dual analysis requires two nite element computations. It is based on the results of displacement and equilibrium approaches of a given problem. It allows to compute the cumulated global discretization error of the two models by a simple comparison of the total energies computed using both methods. This paper presents the development of a new family of equilibrium type tetrahedral nite elements leading to statically admissible solutions of 3D nite element problems. Two examples of dual analysis using these elements are also presented.
