Plastic extremum principle (lower bound) of the plasticity theory for porous materials may be wed for effective design of complex shape elements. Basing on properties of earlier determined systems of discontinuity lines the method of statically admissible stress fields was assumed. The method may be usefully employed in engineering practice for plastic design of porous elements.
