Discrete Structure Shakedown Design Ices ’95, Hawai, July 30 – August 3, 1995

subject

description

The minimum volume shakedown design problem was already approached by several authors with studies devoted to discrete structures (see e.g. [1]–[5]) and to continuous structures (see e.g. [6]). Except some very simple structural typologies, also the optimal shakedown design problem formulations for continuous structures need to be discretized in the application stage. In any case, the relevant optimal shakedown design problem for discrete (or discretized) structures is formulated in terms of design variables as well as behavioural variables, and consists in the search for the/a minimum volume design among all feasible designs (i.e. able to shakedown). Due to its strong non-linearity, the latter problem can be solved only iteratively; so many iterative procedures have been proposed and many computational experiences have been effected to this aim (see e.g. [1]–[6]).
