Abstract

Composite circular discs with polar orthotropic and rectangular orthotropic fibres of different composite materials are modelled and their vibration response due to harmonic point load under thermal environment 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 (BEM) using LMS SYSNOISE.
