Abstract
Magnetorheological elastomers (MREs) are smart composite materials that can change their viscoelastic properties and provide actuation under application of an external magnetic field. In this study, a finite element method is developed in COMSOL Multiphysics to investigate the vibration characteristics of a membrane made of MREs under external applied magnetic field. The aim is to understand the effect of thickness, radius, and boundary conditions of the MRE membrane on its resonance frequencies and mode shapes under varied applied magnetic field. Results will offer valuable insight into how adaptive MRE-based acoustic membranes and metamaterials can be designed and tuned for broad-band noise suppression.
