WebIn shell theory, a special type of curvilinear coordinate system is usually employed. 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. WebJul 12, 2009 · Thick shells with no re rings; plenty of attack & volume.
