Robust topology optimization under loading uncertainties via stochastic reduced order models

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 122, Issue 20, Page 5718-5743, 30 October 2021., 2021
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 ...

Implementation of Structural Assemblies by Simultaneous Projection and Density‐Based Topology Optimization

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
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 ...
