Free Vibration Analysis of a Cross-Ply Laminated Plate in Thermal Environment

Abstract

In this paper, free vibration analysis of a cross-ply laminated plate is investigated under temperature rising with considering temperature-dependent physically properties. Material properties of laminas are orthotropic and temperature-dependent. In the kinematic model of the plate, first shear deformation plate theory is used. In the solution method, the Navier procedure is used for a simply supported plate. The vibration frequencies of the laminated plate are obtained and discussed for different values of temperature, sequence of laminas and orientation angle of layers. Also, the difference between temperature dependent and independent physical properties is investigated.
