Scattering of waves in laminated composite plates

Abstract

A semi-analytical method incorporating various displacement based formulations has been developed to investigate scattering of waves in composite laminated plates. Plane strain condition in composite laminated plate due to propagation of a time harmonicwave and vibrations has been investigated.Various displacement based models have been developed by using combinations of linear, quadratic, cubic and quartic variation of displacements through thickness of the lamina. Results obtained using various displacement models are compared for isotropic, orthotropic and composite laminated plates. The higher order displacement based theory using cubic variation of in-plane and transverse displacements through thickness of lamina is found to be most accurate and economical one for analyzing scattering of waves in composite laminated plates.
