Optimisation of Imperfect Structures using Distributed Components

摘要

This contribution contains an approach to the optimisation of slender compressed structures which leads to designs being robust against geometrical imperfections. In the developed optimisation model, the shape of the structure depends not only on the optimisation variables but also explicitly on a set of imperfection variables. The model of geometrical imperfections is based on the concept of random fields while for the uncertainty analysis a convex model is employed. The implementation of the presented method takes place in a software framework consisting of distributed software components communicating via CORBA. Each of the components is responsible for a certain aspect of the overall problem.
