EXTENSION OF THREE DIMENSIONAL ANALYSIS TO SHELL STRUCTURES USING THE FINITE ELEMENT IDEALIZATION
A three dimensional finite element which is appropriate for use in general shell applications is presented. It is shown that a simple recasting of the element formulation which introduces relative displacements eliminates problems of numerical sensitivity which arise when using standard three dimensional elements in thin shell applications. A technique of incorporating geometric constraints on the permissible displacements of individual nodes is demonstrated. (Modified author abstract)
