Topological sensitivity analysis in large deformation problems
(SpringerNew YorkEUA, 2008)
Topology design of plates considering different volume control methods
(Emerald Group Publishing Limited, 2014-06)
Purpose – The purpose of this paper is to compare between two methods of volume control in the context of topological derivative-based structural optimization of Kirchhoff plates. Design/methodology/approach – The compliance ...
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 ...
Layout and material gradation in topology optimization of functionally graded structures: a global-local approach
(SPRINGER, 2010)
By means of continuous topology optimization, this paper discusses the influence of material gradation and layout in the overall stiffness behavior of functionally graded structures. The formulation is associated to symmetry ...

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 ...
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 ...
