Optymalizacja pierścieni sztywno-plastycznych z więzami geometrycznymi

Andrzej Gawęcki, Andrzej Garstecki

The static approach to optimal plastic design of circular rings with geometric constraints is described in the paper. These constraints consist in an assumption that the cross-section area within the region of a given angle is constant. Solutions of primal and dual problems for rings of sandwich and rectangular cross-section are presented. Final results are compared with the solution obtained by W. Prager [1] where the minimum cross-section constraint had been imposed. Numerical examples show that the form of constraint conditions strongly affect the form of optimal structure and uniqueness of solution.
