A C(Superscript)-Anisoparametric Three-Node Shallow Shell Element for General Shell Analysis

Abstract

A highly desirable three-node shallowly curved shell element is proposed for general shell analysis. Constrained-type C subscript 0 anisoparametric interpolations are derived for the membrane and transverse displacement fields by the use of explicit edge constraints. Pertinent issues on shell theory and infinite element approximation are addressed. Several numerical studies are carried out which demonstrate the effectiveness of this new triangular element in the regime of thin and moderately thick shells. Keywords: Shallow shell; Mindlin theory; Marguerre theory; Finite element analysis; Anisoparametric functions; Kirchoff regime; Penalty relaxation; Edge constraints; Three node triangle.
