A Comparative Study between Mixed and Displacement Model and the Effect of the Numerical Integration in the Axisymmetric Shell Finite Element Analysis

H. Djamal, L. Bachir, and Z. Abdallah
Abstract—In this paper the influence of the choice of the model in the formulation of the axisymmetric shell finite element type is presented. A comparison between results obtained by the use of two elements, CAXI_L and CAXI_K is given. The first element is based on standard mixed formulation Hellinger - Reissner and the second one is formulated with displacement model. The variation of the results according to the number of the Gauss integration points is discussed. A Matlab program is elaborated to calculate the displacements for each element.

Index Terms—Axisymmetric behavior, formulation model, matlab programming, numerical integration.
