    Abstract

    This report presents investigations on the problem of flutter of initially stressed rectangular panels having various types of boundary conditions including the elastic and restraint. using the Galerkins modal analysis technique the solutions are obtained for various cases of panel aspect ratio, thickness ratio,and elastic stiffness of the support.The results show that the flutter mode is primarily determined by the first and the second vibration modes. The results also show that the effect of elastic end can be resonably accurately modelled by simple closed form analytical expressions.
