Topological optimization processes [PDF]

open access: yesGlobal Journal of Engineering and Technology Advances, 2022
The method of topological optimization is based on a mathematical algorithm, which is based on the distribution and intensity of detail stress on the investigated component. It was developed using the Rhino-Grasshopper theory. This is a complicated FEM analysis with the help of the Nastran solver in the Siemens NX software environment.

Optimal Topology Transition

open access: yesIEEE Transactions on Power Systems, 2022
Network topology has significant impacts on operational performance of power systems. While extensive research efforts have been devoted to optimization of network topology for improving various system performances, the problem of how to transition from the initial topology to the desired optimal topology requires study.

Robust topology optimization of three-dimensional photonic-crystal band-gap structures [PDF]

open access: yes, 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 ...

Multi-material topology optimization based on symmetric level set function using the material definition with perfect symmetric property

open access: yesNihon Kikai Gakkai ronbunshu, 2021
This paper provides a vector-valued level set-based topology optimization method for multiple materials. The proposed method is characterized by a perfectly symmetric representation of multi-material by a vector valued level set function, which lowers ...
