Projection Based Reduced Order Model of Elasto-Acoustic Vibrations Computed with Isogeometric Analyses

This paper demonstrates the advantages of Isogeometric Analysis (IGA) over the Finite Element Method (FEM). The study applies IGA to a vibro-acoustic problem, comparing the results with those obtained using an analytical approach and FEM. Specifically, the problem involves a cylindrical cavity surrounded by an external structure. The analysis is carried out in three stages: solving the structural problem, addressing the acoustic problem, and finally tackling the combined vibro-acoustic problem. The comparison highlights the benefits of IGA over traditional Finite Element Analysis.
