Topological Insulators by Topology Optimization [PDF]

open access: yesPhysical 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;

Proportional Topology Optimization under ‎Reliability-based Constraints [PDF]

open access: yesJournal 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.

Geometry and Topology Optimization of Switched Reluctance Machines: A Review

open access: yesIEEE Access, 2022
Switched reluctance machines (SRMs) have recently attracted more interest in many applications due to the volatile prices of rare-earth permanent magnets (PMs) used in permanent magnet synchronous machines (PMSMs).

AuTO: a framework for Automatic differentiation in Topology Optimization [PDF]

open access: yesStructural 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

open access: yesAdvanced 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]

open access: yesComputer 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
