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.

Topologically Optimized Graded Foams
Advanced Engineering Materials, 2023 The adoption of Nature‐inspired strategies to improve materials has fostered the introduction of cavities. But how to mass‐produce structures in which a complex architecture of cavities is point‐to‐point fine‐tuned to the local and global application requirements?

Topology optimization using polytopes [PDF]
Computer Methods in Applied Mechanics and Engineering, 2015 Meshing complex engineering domains is a challenging task. Arbitrary polyhedral meshes can provide the much needed flexibility in automated discretization of such domains. The geometric property of the polyhedral meshes such as the unstructured nature and the facial connectivity between elements makes them specially attractive for topology optimization

Robust topology optimization of three-dimensional photonic-crystal band-gap structures [PDF]
, 2014 We perform full 3D topology optimization (in which "every voxel" of the unit cell is a degree of freedom) of photonic-crystal structures in order to find optimal omnidirectional band gaps for various symmetry groups, including fcc (including diamond ...

Neural networks for topology optimization [PDF]
Russian Journal of Numerical Analysis and Mathematical Modelling, 2019 Abstract In this research, we propose a deep learning based approach for speeding up the topology optimization methods. The problem we seek to solve is the layout problem. The main novelty of this work is to state the problem as an image segmentation task.
