Isogeometric Shape Optimization in Fluid-Structure Interaction
The objective of this work is to examine the potential of isogeometric methods in the context of multidisciplinary shape optimization. We introduce a shape optimization problem based on a coupled fluid-structure system, whose geometry is defined by NURBS (Non-Uniform Rational B-Spline) curves. This shape optimization problem is then solved by using either an isogeometric approach, or a classica...
متن کاملAiaa 2001–1624 Shape Design Optimization of Steady Fluid–structure Interaction Problems with Large Displacements
The objective of this work is to develop and implement efficient numerical procedures for gradient based shape design optimization of steady, strongly coupled fluid–structure interaction problems. Nonlinearities in the analysis arise from both the solid behaviour, the fluid behaviour, and from the deformed interface, where the deformation of the interface is large enough to significantly alter ...
متن کاملMultiphase Shape Optimization Problems
This paper is devoted to the analysis of multiphase shape optimization problems, which can formally be written as min { g ( (F1(Ω1), . . . , Fh(Ωh) ) +m ∣∣ h ⋃ i=1 Ωi ∣∣ : Ωi ⊂ D, Ωi ∩ Ωj = ∅}, where D ⊆ R is a given bounded open set, |Ωi| is the Lebesgue measure of Ωi and m is a positive constant. For a large class of such functionals, we analyse qualitative properties of the cells and the int...
متن کاملOn Some Rescaled Shape Optimization Problems
We consider Cheeger-like shape optimization problems of the form min { |Ω|J(Ω) : Ω ⊂ D } where D is a given bounded domain and α is above the natural scaling. We show the existence of a solution and analyze as J(Ω) the particular cases of the compliance functional C(Ω) and of the first eigenvalue λ1(Ω) of the Dirichlet Laplacian. We prove that optimal sets are open and we obtain some necessary ...
متن کاملAn application of shape optimization in the solution of inverse acoustic scattering problems
We consider the problem of determining the shape of an object immersed in an acoustic medium from measurements obtained at a distance from the object. We recast this problem as a shape optimization problem where we search for the domain that minimizes a cost function that quantifies the difference between the measured and expected signals. The measured and expected signals are assumed to satisf...
