Local a Priori and a Posteriori Error Estimate of TQC9 Element for the Biharmonic Equation

Author(s)

Abstract

In this paper, local a priori, local a posteriori and global a posteriori error estimates are obtained for TQC9 element for the biharmonic equation. An adaptive algorithm is given based on the a posteriori error estimates.

Keywords:

Finite element Biharmonic equation A priori error estimate A posteriori error estimate TQC9 element.
