Vibro-acoustic analysis of composite circular disc with various orthotropic properties

Composite circular discs with polar orthotropic and rectangular orthotropic fibers of different composite materials are modeled and their vibration response due to harmonic point load was computed by finite element method (FEM) using ANSYS. Acoustic response of composite circular disc was computed by coupling the vibration data from FEM to the boundary element method using LMS SYSNOISE. © 2009 IMACS.
