Abstract : The recently derived 'effective stiffness,' velocity corrected Sun plate equation for extensional vibrations are reduced for the case of a plate strip and frequency equations are derived for simply supported edges by the method of M. Levy, where solutions harmonic in plate width are assumed and the boundary conditions for simple supports are automatically satisfied. The results are compared to extensional frequencies for a reduced 'effective modulus' velocity corrected Sun plate theory and for both a velocity corrected and shear corrected Mindlin plate theory with Postma elastic constants introduced.
