Theory Of Anisotropic Shells – Ambartsumyan

In this post, we will see the book Theory Of Anisotropic Shells by V. A. Ambartsumyan.

About the book

Shells are widely used as structural elements in modem construction engineering, aircraft construction, shipbuilding, rocket construction, etc. A careful study of the shells used in engineering leads to the conclusion that they are most often anisotropic (naturally or structurally) and in many cases are anisotropic and laminar.

Despite the large number of articles appearing in journals, there is as yet not one book devoted to the theory of anisotropic laminar shells. In the present book the author partially fills this gap. The text is based on the author’s investigations over the last few years. It consists of the following divisions: (a) fundamental equations of the theory of elasticity of an anisotropic body in curvilinear coordinates; (b) general theory of anisotropic laminar shells; (c) membrane theory of anisotropic shells; (d) theory of symmetrically loaded anisotropic shells of revolution; (e) anisotropic cylindrical shells; (f) shallow anisotropic shells; (g) new theories of aniso­tropic shells and plates.

The book does not deal with the undeniably important problems of non­ linear theory, the theories of stability and vibration, as well as temperature problems of anisotropic laminar shells. Nor does it deal with problems associ­ated with plastic and elastic-plastic deformations of the material of the shell layers, since these problems have not been adequately investigated.
Within each chapter the formulas have a two-part enumeration. Where reference is made to the formulas of preceding chapters a three-part enumer­ation is used (the first digit referring to the chapter).

The book was translated from Russian by was published under NASA Technical Translation series.
