General fundamentals of shellsWe assume that there exist one-to-one relationships between the curvilinear coordinates (GAUSSIAN surface parameters) ξ. (α = 1, 2) and the Cartesian coordinates x. (i = 1, 2, 3) of the points P of a surface (Fig. 11.1).

Membrane theory of shells. The stresses ..are uniformly distributed over the thickness, i.e. only so-called membrane forces occur, but . bending moments and . shear forces are found.

Disksl stresses are assumed uniformly distributed over the thickness, i.e. they do not depend on z. We therefore have a State of Plane Stress for which the most important basic equations in Cartesian and in polar coordinates are summarized in the following, where the thickness of the disk is assumed to be constant.

Algorithms of Mathematical Programming (MP)nding whether the solution algorithm only requires the function values, or also the first and second derivatives of the functions. It will be assumed in this Chapter that in general the functions f, h., g. in . are continuous and at least twice continuously differentiable.
