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 ...

Inverse Design of Energy-Absorbing Metamaterials by Topology Optimization. [PDF]
Adv Sci (Weinh), 2023 Compared with the forward design method through the control of geometric parameters and material types, the inverse design method based on the target stress‐strain curve is helpful for the discovery of new structures.

Shape and topology optimization [PDF]
, 2021 This chapter is an introduction to shape and topology optimization, with a particular emphasis on the method of Hadamard for appraising the sensitivity of quantities of interest with respect to the domain, and on the level set method for the numerical representation of shapes and their evolutions.

Topological optimization processes [PDF]
Global 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.
