A method based on an assumption that the radial bending moment is zero at a nodal circle is shown to yield accurate estimates of natural frequencies correspon'ding to higher modes of transversely vibrating polar orthotropic annular plates for various combinations of clamped, simply supported and fre

The non-axisymmetric instability of polar orthotropic annular plates under inplane uniform radial pressures is studied by use of the shooting method. The characteristic equations and eigenvalues under a variety of edge conditions are given. Under two appropriate hypotheses, we prove that all eigenva
