Abstract An isogeometric coupling algorithm based on the finite element method and the boundary element method
(IGA-FEM/BEM) is proposed for the simulation of acoustic fluid-structure interaction and structuralacoustic topology optimization using the direct differentiation method. The geometries are constructed
from triangular control meshes through Loop subdivision scheme. The effect of sound-absorbing materials
on the acoustic response is characterized by acoustic impedance boundary conditions. The optimization
problem is formulated in the framework of Solid Isotropic Material with Penalization methods and the sound
absorption coefficients on elements are selected as design variables. Numerical examples are presented to
demonstrate the validity and efficiency of… More >
