The paper summarizes the finite element analysis procedure and discusses the approximations that are introduced in the analysis of thin shell structures. A wide range of different finite elements that have been developed for the analysis of thin shells are described, including both curved as well as planar types. Comparative performances of the different elements in the analysis of several example shell structures are described. Some conclusions are drawn with respect to the relative merit of the various elements.
