Design of bi-metallic devices based on the topological derivative concept
(Pergamon-Elsevier Science Ltd., 2015-01)
In this work the topological derivative concept is applied in the context of topology design of thermo-mechanical devices, where the linear elasticity system (modeled by the Navier equation) is coupled with the steady-state ...
Piezoresistive device optimization using topological derivative concepts
(Springer, 2014-10)
A piezoresistive sensor is composed of a piezoresistive membrane attached to a flexible plate. The piezoresistive material is anisotropic, and its electrical properties change when subjected to mechanical stresses. In this ...
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 ...
Topological sensitivity analysis for a two-parameter Mooney-Rivlin hyperelastic constitutive model

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 ...
Topological sensitivity analysis in large deformation problems

Topology design of thermomechanical actuators combined with heat source optimization
(Yokohama Publishers, 2019-11)
In the paper a problem of optimal topology and shape design of thermo-mechanical actuators with the heat source support is considered. The objective is to maximize the output displacement in a prescribed direction on the ...
On the detection of several obstacles in 2d stokes flow: topological sensitivity and combination with shape derivatives

Two new topological indices to differentiate high and low inhibitory activity of diphenyl sulfone derivatives
(SOCIEDAD CHILENA DE QUIMICA, 2003-06)
This work presents two new topological indices, C(u) and C-A(u), that permit their application to organic molecules containing oxygen, nitrogen, sulfur and halogens. These indices are obtained by modifying Schultz molecular ...
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 ...
