Postprocessing and improved accuracy of the lowest-order mixed finite element approximation for biharmonic eigenvalues Conference Paper

abstract

• The mixed finite element method for the biharmonic eigenvalue problem using linear or bilinear finite elements is considered. The paper is based on approach described by the same authors in [1], where polynomials of degree n, n 2, were used. The case of linear finite elements was studied by Ishihara in [5], where an error estimate of rate (h1/2) for the eigenvalues and the eigenfunctions was established. Using postprocessing we derive an improved convergence rate for the approximate eigenvalues, namely (h). This result is confirmed by model numerical experiments.
