Abstract

In this paper we focus on the adaptation to topology optimization of a previous variance-expected compliance applied to truss design. The principal objective of such a model is to find robust structures for a given main load and its perturbations. In particular we are interested in avoiding high compliance values in cases of important perturbations. In the first part, we recall the varianceexpected formulation and main results in the case of truss structures. Then, we extend this model to topology optimization. Finally, we study the interest of this model on a 2D benchmark test.
