In the article we will consider cylindrical shells, their definition and properties of cylindrical shells, as well as examples of their application. We will also consider methods for calculating cylindrical shells. A cylindrical shell is a geometric body formed by turning a rectangle around one of its sides. The result is a cylinder whose bases are two parallel and equal rectangles, and the side surface is a surface formed by rotating the rectangle around one of its sides. Cylindrical shells have two main elements – the base and the side surface. The bases of the cylindrical shell are parallel and equal rectangles, and the side surface is a surface formed by rotating the rectangle around one of its sides. A cylindrical shell with filling is considered. They are in an axisymmetric stress state. The case is considered when the filler has the shape of a hollow cylinder or an elastic cone. The results of calculations for each case are presented.
