The mathematical description of the properties of a shell is much more elaborate than those of beam and plate structures. Therefore many engineers and architects are unacquainted with aspects of shell behaviour and design, and are not familiar with s

In this chapter we will extend the membrane theory for shells of arbitrary curvatures, as presented in Chap. 3, to a theory in which we account for both membrane and bending action. This theory, developed by Donnell [1], is applicable to shallow shel

The basic assumption of membrane theory is that a thin shell produces a pure membrane stress field, and that no bending stresses occur. This assumption is applicable if certain boundary and loading conditions, exemplified in Chap. 1, are met. In this

As stated in Sect. 4.9, the axisymmetry of the load for a circular cylindrical shell means that the axial load component \( p_{x} \) and normal load component \( p_{z} \) are uniformly distributed along the circumference, and the circumferential load

For a circular cylindrical shell, it is convenient to apply a polar co-ordinate system to the cross-sectional profile as illustrated in Fig. 4.1. The axes are chosen in the longitudinal, circumferential and transverse directions.

Tens of years ago, theories were proposed for the edge disturbance problem in shells of revolution. Because a rigorous bending theory is complicated, attempts were made for reliable approximations. A well-known one was published by Geckeler [1, 2], w

The three sets of equations of Chap. 2 derived for the membrane behaviour of thin shells relate to a co-ordinate system placed according to the principal curvatures. In practice it may be useful to choose the co-ordinate system in such a way that a c

This book is concerned with thin elastic shells. A thin shell has a very small thickness-to-minimal-radius ratio, often smaller than 1/50. As with plates, an applied load that acts out-of-plane leads to larger displacements than those generated by a
