Part of the International Centre for Mechanical Sciences book series (CISM, volume 332)


In the present paper a general formulation of optimal design problems is firstly proposed, and the variational method founded on Lagrangian multiplier technique is shown. As an application a simple example for optimal plastic design of beams is solved.

The variational formulation is discussed in detail for the case of plastic design of circular plates: optimality criterion is shown and special features of optimal solutions are discussed.

Then the same problem is proposed in a discretized form, which makes use of a finite different technique and leads to a linear programming formulation. The features of such an approach are discussed and numerical solutions are shown as well.
