1. Procedure
2. As regards number and placement of elements to represent the shell, five trials were made. First, the shell was represented by 10 equal elements as shown in Fig. 5a. Maintaining this layout of elements, calculations were made of the six quantities of interest in connection with the stresses using each of the polynomial expansions (1), (2), and (3) in the elements. The results of these calculations are compared with the exact theory in Figs. 6-11. There was no mixing of expansions among the elements; that is, when expansion (1) was used in any one element it was used in all elements and similarly for expansions (2) and (3). The representation
