Paper continues developments and numerical testing of functional approach [1-3] to
a posteriori error control for 2D problems of classical [2] and Cosserat elasticity [4,5]. The
approach yields reliable error bounds (majorants) that are valid for all conforming solutions of
problems regardless of methods used for a numerical implementation of a solution process.
Efficiency of the above technique is shown on a set of numerical examples including
consequent mesh adaptations with MATLAB tools as it was done [6].
Keywords: computational mechanics; a posteriori error estimates; finite element method. |
