Topology Verification for Isosurface Extraction
(IEEE COMPUTER SOCLOS ALAMITOS, 2012-06)
The broad goals of verifiable visualization rely on correct algorithmic implementations. We extend a framework for verification of isosurfacing implementations to check topological properties. Specifically, we use stratified ...
Symmetry considerations for topology design in the elastic inverse homogenization problem
(Pergamon-Elsevier Science Ltd, 2019-07)
An analysis of the symmetries characterizing the micro-architecture topologies and the elastic material properties is performed. The goal is to elucidate a systematic procedure that facilitates the design of elastic ...
Topology design of 2D and 3D elastic material microarchitectures with crystal symmetries displaying isotropic properties close to their theoretical limits
(Elsevier, 2019-11)
This paper evaluates the effect that different imposed crystal symmetries have on the topology design of two-phase isotropic elastic composites ruled by the target of attaining extreme theoretical properties. Extreme ...
Integral Piezoactuator System with Optimum Placement of Functionally Graded Material - A Topology Optimization Paradigm
(SAGE PUBLICATIONS LTD, 2010)
Piezoactuators consist of compliant mechanisms actuated by two or more piezoceramic devices. During the assembling process, such flexible structures are usually bonded to the piezoceramics. The thin bonding layer(s) between ...
Topological Derivative-Based Topology Optimization of Plate Structures Under Bending Effects
(Springer, 2021-02)
In this work, the topological derivatives of L2 and energy norms associated with the solution to Kirchhoff and Reissner-Mindlin plate bending models are introduced. Based on existing theoretical results, closed forms of ...
Design of compliant mechanisms considering thermal effect compensation and topology optimization
(ELSEVIER SCIENCE BV, 2010)
Compliant mechanisms can achieve a specified motion as a mechanism without relying on the use of joints and pins. They have broad application in precision mechanical devices and Micro-Electro Mechanical Systems (MEMS) but ...
Design of fluid components using the topological optimization method
(Emerald, 2019-06-10)
Purpose – The purpose of this paper is to present applications of the topological optimization method dealing with fluid dynamic problems in two- and three dimensions. The main goal is to develop a tool package able to ...
Material design of elastic structures using Voronoi cells
(John Wiley & Sons Ltd, 2018-07)
New tools for the design of metamaterials with periodic microarchitectures are presented. Initially, a two-scale material design approach is adopted. At the structure scale, the material effective properties and their ...
Piezoresistive sensor design using topology optimization
(SPRINGER, 2008)
Piezoresistive materials, materials whose resistivity properties change when subjected to mechanical stresses, are widely utilized in many industries as sensors, including pressure sensors, accelerometers, inclinometers, ...
Topology optimization of buildings subjected to stochastic base excitation
(2020)
In seismically active regions, buildings are inevitably exposed to extreme ground motions. Traditionally, the main structural system is designed iteratively to resist these loads, which provides safe systems, but is usually ...
