Optimum Design of Structures Made of Elastic-Plastic Materials,th unknown boundaries and partial derivatives are investigated by the methods of distributed parameter control theory. The necessary optimality conditions for unknown boundaries are obtained taking into account load carrying capacity and shakedown constraints. The derived sensitivity analysis formul

Optimal Plastic Design of Plates, Shells and Shellgrids, arrived at. Of particular significance is the finding that the minimum weight design of solid plates and shells with a maximum thickness constraint contains a theoretically infinite number of rib-like formations. At relatively low load intensities, the layout of such ribs is furnished by the classi

Optimization of Cylindrical Shells Under Combined Loading Against Brittle Creep Rupture,aterial is assumed to be governed by the Norton-Odqvist nonlinear steady creep law. Minimal weight of the shell is the design objective, radius and wall thickness are design variables, and the constraint refers to brittle creep rupture as described by the Kachanov-Sdoburev hypothesis. Elimination of
