Acoustic Transmission Loss Through Multilayer Periodic Elastic Structures
Application ID: 26841
In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. The effects of incident angle, frequency, and damping is studied.
Important features used: Acoustic-structure interaction with arbitrary incident angle, scattered field formulation, the perfectly matched layer (PML), and periodic Floquet boundary conditions.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
