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.
