Abstract: This study conducts an investigation into the vibro-acoustic behavior of polymer nano composites reinforced with functionally graded graphene. The numerical analysis is conducted using both finite element method and Rayleigh integral. Free and forced vibration characteristics are conducted to understand the sound characteristics in depth. The influence of various parameters such as type of functional grading, loading and boundary conditions are also observed. Results shows that natural frequency of a structure is heavily dependent on the type of functional grading of the structure, while the mode shapes are observed to be impervious to these changes. The type of functional grading is also seen to influence the resonant amplitude of vibration and acoustic response. This influence is duly produced in the bandwise calculation of sound power which suggests that FG-X distribution of graphene is to be used for lower frequency levels. © 2020 Author(s).
