A SCHEME WITH OPTIMAL ORDER OF SUPER-CONVERGENCE BASED ON EEP METHOD: II NUMERICAL RESULTS

Based on the Element Energy Projection (EEP) method, an improved scheme with optimal order of super-convergence, is presented for one-dimensional C⁰ FEM, i.e. FEM sulotions can be obtained through the scheme for the elements with sufficient smooth property and m degrees. The proposed scheme is capable of producingO(h^2m) super-convergence for both displacements and stresses at any point on an element in post-processing stage. The whole work consists of three parts, i.e. formulation, numerical results and mathematical analysis. The present paper is the second in the series and gives numerical algorithm and experimental results, which support the formulation proposed in the first part of the whole work.
