Soft shells

The book deals with the equilibrium of soft shells. The shells are of zero thickness and are not extensible. The deformation of the shells consists of bends and from contractions into folded zones. The theory is stated. Equilibrium problems are solved under the hydrostatic pressure of shells, having before the deformation the shape of a flat strip, a circular cylinder, a hemisphere, a spherical segment. The book is intended for applied mathematicians, specialists in the theory of shells.
