Ecodesign with topology optimization
Procedia CIRP, 2022 In order to mitigate the impact of the transportation sector on climate change, light and ecological parts must be designed. A lifecycle oriented design methodology with C02 footprint minimization of parts used in various transports is presented in this work.

Proportional Topology Optimization under Reliability-based Constraints [PDF]
Journal of Applied and Computational Mechanics, 2022 Topology optimization is a methodology widely used in the design phase that has gained space in engineering. On the other hand, uncertainty is present in material properties, loads, and boundary conditions in practically any design.

TopologyGAN: Topology Optimization Using Generative Adversarial Networks Based on Physical Fields Over the Initial Domain [PDF]
Journal of Mechanical Design, 2020 In topology optimization using deep learning, the load and boundary conditions represented as vectors or sparse matrices often miss the opportunity to encode a rich view of the design problem, leading to less than ideal generalization results.

Topological Insulators by Topology Optimization [PDF]
Physical Review Letters, 2019 An acoustic topological insulator (TI) is synthesized using topology optimization, a free material inverse design method. The TI appears spontaneously from the optimization process without imposing requirements on the existence of pseudo spin-1/2 states at the TI interface edge, or the Chern number of the topological phases. The resulting TI is passive;

Multiobjective Topology Optimization of Spatial-Structure Joints
Advances in Civil Engineering, 2021 To realize the static and dynamic multiobjective topology optimization of joints in spatial structures, structural topology optimization is carried out to maximize the stiffness under static multiload conditions and maximize the first third-order dynamic

Topology optimization for quasistatic elastoplasticity
ESAIM: Control, Optimisation and Calculus of Variations, 2022 Topology optimization is concerned with the identification of optimal shapes of deformable bodies with respect to given target functionals. The focus of this paper is on a topology optimization problem for a time-evolving elastoplastic medium under kinematic hardening.

AuTO: a framework for Automatic differentiation in Topology Optimization [PDF]
Structural And Multidisciplinary Optimization, 2021 A critical step in topology optimization (TO) is finding sensitivities. Manual derivation and implementation of sensitivities can be quite laborious and error-prone, especially for non-trivial objectives, constraints and material models.

Multilevel topology optimization [PDF]
Computer-Aided Design and Applications, 2017 The paper proposes an extension of the Function-Behaviour-Structure (FBS) framework to multi-levelc design representation. The ontology based on function, behaviour and structure has been enriched with a new design entity, the topology, with the aim of connecting more levels of representation.

Inverse design in photonics by topology optimization: tutorial [PDF]
Journal of the Optical Society of America B, 2020 Topology optimization methods for inverse design of nano-photonic systems have recently become extremely popular and are presented in various forms and under various names. Approaches comprise gradient and non-gradient based algorithms combined with more
