A consistent relaxation of optimal design problems for coupling shape and topological derivatives
(2018-09)
Article
Open AccessIn this article, we introduce and analyze a general procedure for approximating a ‘black and white’ shape and topology optimization problem with a density optimization problem, allowing for the presence of ‘grayscale’ ... -

Symmetry considerations for topology design in the elastic inverse homogenization problem
(2019-07)
Article
Restricted access - publisher's policyAn analysis of the symmetries characterizing the micro-architecture topologies and the elastic material properties is performed. The goal is to elucidate a systematic procedure that facilitates the design of elastic ... -
Topology design of 2D and 3D elastic material microarchitectures with crystal symmetries displaying isotropic properties close to their theoretical limits
(Elsevier, 2020-03)
Article
Restricted access - publisher's policyThis paper evaluates the effect that different imposed crystal symmetries have on the topology design of two-phase isotropic elastic composites ruled by the target of attaining extreme theoretical properties. Extreme ... -
