Mine is, firstly, that plate theory is not well represented in the available elementary texts, and secondly that no existing text adequately covers modern applications. The present account is intended to be elementary (though this is a relative term) while still providing stimulation and worthwhile experience for the reader. Special features of interest will I hope be the treatment of geometry of surfaces and the attempts around the end of the work to speculate a little. The detailed treatment of geometry of surfaces has been placed in an appendix where it can readily be referred to by the reader. My interest in plate theory extends back many years to the energetic and stimulating discussions with my supervisor, Professor R. W. Tiffen, at Birkbeck College, London, and a debt to him remains. Interest was rekindled for me by Dr R. E. Melchers when I supervised him in Cambridge some ten years ago, and more recently my stay at Strathclyde University and encouragement and stimulation in the Civil Engineering Department led me to undertake the present work.

Abstract
The topic to be studied is the mechanics of plates. First, what is a plate? Here a plate will be defined to be a plane, load-carrying element in a structure which is comparatively thin in comparison with the plate surface dimensions. Typical examples of plates in practical applications are floor slabs in buildings, decking on bridges, load-bearing wall structures, ship hull plating and many other constructions. Plate elements may be large, spanning tens of metres in buildings or bridges, or very small when incorporated as a diaphragm in a pressure reduction valve. In all cases however the elements have thicknesses which are a tenth to a twentieth or less of the radius of the valve diaphragm, or span of the slab.

Abstract
In the Appendix the geometry of surfaces is developed. Relevant results will be used here for purposes of developing a suitable plate theory. The themes are the . of a bent plate and the . of plate bending. As remarked earlier, plates are essentially two-dimensional beam-type structures. In particular, the main interest is in plates which span transversely (horizontally say) and are loaded laterally (vertically say). Such a configuration produces a . system in the plate.

Abstract
The earlier chapters have dealt with statics and kinematics of plate bending. That is, they have dealt with the conditions which the internal forces and moments must satisfy if they are to be in equilibrium with the loads; also, the methods have been developed for describing the deformation of the plate in its bent state. Before actual problems of plate bending can be formulated and solved, these two aspects have to be brought together, and in this chapter this is done for the case of the elastic plate. Roughly speaking, plates respond elastically in the working load condition, and plastically at the ultimate or collapse state. This chapter will be dealing with plates at working load, and the next will deal with plastic plates, namely plates in the final stages of loading before they collapse.

Abstract
As remarked in Chapter 3, a plate near to collapse is likely to be in a plastic condition, whereas a plate at working load is likely to be in an elastic state. Compared with elastic plates, plastic response in plates is more varied, since it depends upon the nature of the plate material as to quite what response is to be expected.

Abstract
The emphasis in the previous chapters has been on the study of isotropic plates. As very many practical plates are isotropic, the emphasis on isotropy is reasonable, but there are also valid reasons for making a separate study of anisotropy, which is the central theme of this chapter.

Abstract
There is an extensive amount of material available on the subject of plate theory. Our problem here is one of selection. The first title to Be mentioned should perhaps be S. P. Timoshenko’s . (McGraw-Hill), first published in 1940, with a second edition (in collaboration with S. Woinowsky-Krieger) in 1959. As the title implies, shells as well as plates are dealt with, but the plates are static elastic plates only. The elastic stability of plates is dealt with in Timoshenko’s companion work, . (McGraw-Hill), first published in 1936 and re-edited (in collaboration with J. M. Gere) in 1961. These are both standard works, rather than elementary textbooks.
