For an isotropic circular plate with constant thickness and free edges, its fundamental vibration mode takes the form of a twisting mode with two nodal diameters, i.e. n ΒΌ 2. In certain applications, it may be necessary to have an axisymmetric shape for the fundamental vibration mode (i.e. mode shap
