The membrane shell theory is used extensively in designing such structures as flat-bottom tanks, pressure vessel components (Fig. 6-1) and dome roofs. The membrane theory assumes that equilibrium in the shell is achieved by having the in-plane membrane forces resist all applied loads without ...
This chapter discusses the membrane theory for shells of general shape. Before considering the membrane stress analysis of such a shell, it is necessary to derive some elementary formulae defining the geometry of the middle surface. A surface may be generated from a series of straight lines paral...
An analysis of the membrane electroelastic state and the determination of the first vibration eigenfrequencies are often of particular interest in the analysis of thin-walled elements. It is shown how the error of membrane theory can be reduced considerably by introducing certain additional terms ...

1.A thin, flexible layer of tissue that covers, lines, separates, or connects cells or parts of an organism. Seecell membrane. 2.ChemistryA thin sheet of natural or synthetic material that is permeable to substances in solution. The American Heritage® Student Science Dictionary, Second Editio...
Natural structural shapes for shells of revolution in the membrane theory of shells Natural Structural Shapes are derived for axisymmetrically loaded shells of revolution within the membrane theory of shells. The concept of natural structural shapes is based on the simultaneous minimization of the mass...
