Robust topology optimization under loading uncertainties via stochastic reduced order models
Abstract An efficient approach for topology optimization under uncertainty is presented. Stochastic reduced order models (SROMs) are leveraged for the modeling and propagation of uncertainties within a robust topology optimization (RTO) formulation. The SROM approach provides an alternative to existing uncertainty quantification methods and yields a ...

This article proposed a methodology that combines two well‐known projections and modified density‐based optimized techniques in one formulation methodology. This methodology contains an effective explicit geometric entity identified by shape variables that provide easy control in desired particular regions; implicit density‐based topological ...

Robust topology optimization for structures under interval uncertainty [PDF]
© 2016 Elsevier Ltd. All rights reserved. This paper proposes a new non-probabilistic robust topology optimization approach for structures under interval uncertainty, as a complementarity of the probabilistic robust topology optimization methods. Firstly,
