Abstract
The current paper compares the finite element simulation of an arbitrary shell structure using two different finite element formulations. The first one is a shell element, where the curvature of the structure in inherent to the element. The second is an assembly of plate elements in space, in order to form a similar shell structure, but the formulation is of a flat element. The paper compares the convergence of the results from the two distinct formulations and presents the resulting boundary reactions for each assembly. The curvature is usually not considered in the calculation of reactions in commercial finite element software, but it is shown in this paper to have relevancy in the obtained results.
