Structural shape optimization by IGABEM and particle swarm optimization algorithm
(Elsevier, 2018)
In this paper, a new approach is developed for structural shape optimization, which consists in coupling the particle swarm optimization (PSO) algorithm and the isogeometric boundary element method (IGA-BEM). The IGA-BEM ...
Newton's method for solving optimal shape design problems
In this chapter we present some results related to Newton's method in order to extend the solvability of optimal shape design problems. Moreover, some numerical examples are also presented in the chapter.
A General Meta-graph Strategy for Shape Evolution under Mechanical Stress
(Taylor and Francis Inc., 2019-01-01)
The challenges that a shape or design stands are central in its evolution. In the particular domain of stress/strain challenges, existing approaches eliminate under-demanded neighborhoods from the shape, thus producing the ...

Optimal Shape of an Underwater Moving Bottom Generating Surface Waves Ruled by a Forced Korteweg-de Vries Equation
(Springer New York LLC, 2019)
© 2018, Springer Science+Business Media, LLC, part of Springer Nature.It is well known since Wu and Wu (in: Proceedings of the 14th symposium on naval hydrodynamics, National Academy Press, Washington, pp 103–125, 1982) ...
Adaptive finite element method for shape optimization
(Cambridge University Press, 2012-10)
We examine shape optimization problems in the context of inexact sequential quadratic programming. Inexactness is a consequence of using adaptive finite element methods (AFEM) to approximate the state and adjoint equations ...
Structural shape optimization of 3D nearly-incompressible hyperelasticity problems
(Latin Amer J Solids StructuresSao PauloBrasil, 2008)
Continuous Optimization in Aerospace Structures
(John Wiley & Sons Ltd, 2010)
In structural design optimization, engineers and designers aim to obtain more efficient designs with regards to weight, stiffness and frequency measures, for a given set of design variables. These design variables can be ...
An unfitted hybridizable discontinuous galerkin method in shape optimization.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Ingeniería Matemática., 2022)
Shape optimization seeks to optimize the shape of a region where certain partial differential
equation is posed such that a functional of its solution is minimized/maximized. In this thesis we
give an introduction to ...
