Topology Optimisation under Uncertainties with Neural Networks
Algorithms, 2022 Topology optimisation is a mathematical approach relevant to different engineering problems where the distribution of material in a defined domain is distributed in some optimal way, subject to a predefined cost function representing desired (e.g ...

The Topological State Derivative: An Optimal Control Perspective on Topology Optimisation. [PDF]
J Geom Anal, 2023 AbstractIn this paper, we introduce the topological state derivative for general topological dilatations and explore its relation to standard optimal control theory. We show that for a class of partial differential equations, the shape-dependent state variable can be differentiated with respect to the topology, thus leading to a linearised system ...

Topology Optimisation of Wideband Coaxial-to-Waveguide Transitions. [PDF]
Sci Rep, 2017 AbstractTo maximize the matching between a coaxial cable and rectangular waveguides, we present a computational topology optimisation approach that decides for each point in a given domain whether to hold a good conductor or a good dielectric. The conductivity is determined by a gradient-based optimisation method that relies on finite-difference time ...

Topological invariance in whiteness optimisation
Communications Physics, 2023 AbstractMaximizing the scattering of visible light within disordered nano-structured materials is essential for commercial applications such as brighteners, while also testing our fundamental understanding of light-matter interactions. The progress in the research field has been hindered by the lack of understanding how different structural features ...

Topology Optimisation: A case study. [PDF]
IABSE Conference, Bath 2017: Creativity and Collaboration – Instilling Imagination and Innovation in Structural Design, 2017 Parametric and computational design play a major role in contemporary architecture and engineering. Designers need no longer conform to predetermined shapes and sections, but are given freedom to explore new geometries and structural forms. An example of how an organic process can be employed to finding the solution to a design problem is presented ...

Topology Optimisation of Piston
International Journal for Research in Applied Science and Engineering Technology, 2023 Abstract: This research paper presents a comprehensive study on the topology optimization of a piston component manufactured through 3D printing technology. The study employs a combination of SolidWorks and ANSYS software to model and simulate the piston's structural behavior under different loading conditions.

Computing via material topology optimisation [PDF]
Applied Mathematics and Computation, 2018 We construct logical gates via topology optimisation (aimed to solve a station problem of heat conduction) of a conductive material layout. Values of logical variables are represented high and low values of a temperature at given sites. Logical functions are implemented via the formation of an optimum layout of conductive material between the sites ...
