154 Analytical Solution for Free Vibration Design Sensitivity of Simply Supported, Symmetrical Laminated Rectangular Plate

Abstract

The design sensitivity is very important information for designing and manufacturing composite material structures. In the present report, a certain type of sensitivity problem is studied for free vibration of symmetrically laminated rectangular plates simply supported along the edges. An analytical solution for sensitivity of natural frequencies is presented. Then the present solution is applied to some numerical examples of the plates, and the accuracy and effectiveness are verified.
