The middle surface of the shell is defined by X = X (x,y),Y = Y (x,y), and Z = Z (x,y), where X,Y,Z are rectangular coordinates and x, y are surface coordinates. The normal distance from the middle surface in the thickness direction is denoted by ± z.

WebA concrete shell, also called “thin shell” concrete structure, is composed of a thin shell of concrete formed in such a way as to be self-supporting, often with no interior columns or exterior buttresses. The shells are most commonly flat plates and domes. They can also take the form of ellipsoids or cylindrical sections.
