Sensitivity Hot Spot Penalization: A Robust Topology Optimization Framework against First-Order Worst-Case Perturbations
Junpeng Wang, Niels Aage, Ole Sigmund
Deterministic topology optimization can efficiently generate high-performance structural designs, but it does not explicitly control localized fragility induced by manufacturing va…
A practical review on promoting connectivity in topology optimization
Vanessa Cool, Niels Aage, Ole Sigmund
Topology optimization facilitates the automated design of high-performance structures across various engineering fields but, if unconstrained, often produces designs that are compl…
Anatomically and mechanically conforming patient-specific spinal fusion cages designed by full-scale topology optimization
Thijs Smit, Niels Aage, Daniel Haschtmann +2
Cage subsidence after instrumented lumbar spinal fusion surgery remains a significant cause of treatment failure, specifically for posterior or transforaminal lumbar interbody fusi…
Efficient Inverse-designed Structural Infill for Complex Engineering Structures
Peter Dørffler Ladegaard Jensen, Tim Felle Olsen, J. Andreas Bærentzen +2
Inverse design of high-resolution and fine-detailed 3D lightweight mechanical structures is notoriously expensive due to the need for vast computational resources and the use of ve…
Topology optimization of transient vibroacoustic problems for broadband filter design using cut elements
Cetin B. Dilgen, Niels Aage
The focus of this article is on shape and topology optimization of transient vibroacoustic problems. The main contribution is a transient problem formulation that enables optimizat…
On the use of Artificial Neural Networks in Topology Optimisation
Rebekka V. Woldseth, Niels Aage, J. Andreas Bærentzen +1
The question of how methods from the field of artificial intelligence can help improve the conventional frameworks for topology optimisation has received increasing attention over…
De-homogenization using Convolutional Neural Networks
Martin O. Elingaard, Niels Aage, J. Andreas Bærentzen +1
This paper presents a deep learning-based de-homogenization method for structural compliance minimization. By using a convolutional neural network to parameterize the mapping from…
Synthesis of Frame Field-Aligned Multi-Laminar Structures
Florian Cyril Stutz, Tim Felle Olsen, Jeroen Peter Groen +4
In the field of topology optimization, the homogenization approach has been revived as an important alternative to the established, density-based methods because it can represent t…
Large scale three-dimensional manufacturing tolerant stress-constrained topology optimization
Gustavo Assis da Silva, Niels Aage, André Teófilo Beck +1
In topology optimization, the treatment of stress constraints for very large scale problems has so far not been tractable due to the failure of robust agglomeration methods, i.e. t…
De-homogenization of optimal multi-scale 3D topologies
Jeroen Groen, Florian Stutz, Niels Aage +2
This paper presents a highly efficient method to obtain high-resolution, near-optimal 3D topologies optimized for minimum compliance on a standard PC. Using an implicit geometry de…
Adaptive Reduced-Order Modeling for Non-Linear Fluid-Structure Interaction
Ali Thari, Vito Pasquariello, Niels Aage +1
We present an adaptive reduced-order model for the efficient time-resolved simulation of fluid-structure interaction problems with complex and non-linear deformations. The model is…
Topology optimization of microwave waveguide filters
Niels Aage, Villads Egede Johansen
We present a density based topology optimization approach for the design of metallic microwave insert filters. A two-phase optimization procedure is proposed in which we, starting…
Infill Optimization for Additive Manufacturing -- Approaching Bone-like Porous Structures
Jun Wu, Niels Aage, Ruediger Westermann +1
Porous structures such as trabecular bone are widely seen in nature. These structures exhibit superior mechanical properties whilst being lightweight. In this paper, we present a m…
