Abstract

Genetic algorithm for shape optimization of acoustic scattering bodies E. Divo\ M. Ingber^, and A. J. Kassab* ^Department of Mechanical, Materials, and Aerospace Engineering University of Central Florida, 32816-2450, USA ^Department of Mechanical Engineering University of New Mexico, Albuquerque, New Mexico, 87131, USA Abstract Shape optimization of acoustic scattering bodies is carried out using genetic algorithms (GA) coupled to a boundary element method for exterior acoustics. The BEM formulation relies on a modified Burton-Miller algorithm to resolve exterior acoustics and to address the uniqueness issue of the representation problem associated with the Helmholtz integral equation at the eigenvalues of the associated interior problem. 1. Introduction Shape optimization of acoustic scattering bodies is achieved using genetic algorithms (GA) as a minimization tool coupled to a boundary element method solver for the exterior acoustics problem. The BEM formulation
