Topological sensitivity analysis in heterogeneous anisotropic elasticity problem. Theoretical and computational aspects
(Elsevier Science Sa, 2016-11)
The topological sensitivity analysis for the heterogeneous and anisotropic elasticity problem in two-dimensions is performed in this work. The main result of the paper is an analytical closed-form of the topological ...
Topology optimization of 2D elastic structures using boundary elements
(Elsevier, 2008-07-03)
Topological optimization provides a powerful framework to obtain the optimal domain topology for several engineering problems. The topological derivative is a function which characterizes the sensitivity of a given problem ...
Photo-electrons unveil topological transitions in graphene-like systems
(Nature Publishing Group, 2016-11-11)
The topological structure of the wavefunctions of particles in periodic potentials is characterized by the Berry curvature Ωkn whose integral on the Brillouin zone is a topological invariant known as the Chern number. The ...
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 ...
Topology design of thermomechanical actuators
(Springer, 2017-05)
The paper deals with topology design of thermomechanical actuators. The goal of shape optimization is to maximize the output displacement in a given direction on the boundary of the elastic body, which is submitted to a ...
Topological derivative-based optimization of micro-structures considering different multi-scale models
(Tech Science Press, 2010)
A recently proposed algorithm for micro-structural optimization, based on the concept of topological derivative and a level-set domain representation, is applied to the synthesis of elastic and heat conducting bi-material ...
Catalog of Andreev spectra and Josephson effects in structures with time-reversal-invariant topological superconductor wiresCentro Internacional de Estudios Avanzados
(American Physical Society, 2019-02-20)
We study all the possible different two-terminal configurations of Josephson junctions containing wires of time-reversal-invariant topological superconductors and ordinary superconductors, including combinations with an ...
Structural, Electronic, Topological and Vibrational Properties of Isomers of Thymidine ? A Study Combining Spectroscopic Data with DFT Calculations
(Human Journals, 2017-12)
In this work, the structural, electronic, topological and vibrationalproperties of six Cis and Trans isomers of Thymidine (THY) in gasand aqueous solution phases were studied combining the hybridB3LYP/6-31G* method with ...
Topological synthesis of planar metamorphic mechanisms for low-voltage circuit breakers
(Taylor, 2012-10)
This article presents a systematic graph theory-based method for the topological synthesis of planar metamorphic mechanisms including metamorphic transformations of links and changes in the degrees-of-freedom. The parts ...
