In the preceding chapters dealing with the membrane theory of shells, we often met questions which this theory could not answer. This indicates that in certain cases the bending stiffness of the shell,. although small, cannot be disregarded and that it is necessary to develop a bending theory. In such a theory all the stress resultants defined by (1.1 a—j) will appear, and, as one may easily imagine, the mathematical analysis of such stress systems is far from simple. Therefore, solutions have been obtained for only a few of the simplest types of shells. They will be presented in this chapter and the next.
