Abstract
A dynamic Analysis of thin rectangular plates made of anisotropic materials is treated. The analysis is based on the assumptions of classical plate theory in which the anisotropic characteristics of the plate material are introduced. The static lateral load on the plate is replaced by D' Alembert inertia load. The free vibration of simply supported rectangular orthotropic plates is treated as numerical examples, the obtained results are compared with the three dimensional elasticity solution. To verify the theoretical analysis, an experimental study is done using 8 layers woven cross play fiber glass/epoxy rectangular plates.
