Development and Application of the p-version of the Finite Element Method.

Abstract

The p-version of the finite element method is a new, important, computationally efficient, approach to finite element analysis. It is more robust than the conventional h-version and its rate of convergence, for domains with corners and for other singularity problems, is twice that of the h-version. Hierarchic elements which implement the p-version efficiently have been formulated so as to enforce C(0) or C(l) continuity in the planar case, and so as to enforce C(0) continuity in three dimensions. Keywords: Finite Element Analysis; Stress Analysis; Hierarchic Families of Finite Elements; p version of the Finite Element Method; Stress Intensity Factors; Numerical Analysis.
