At low frequencies, the Lamb phase velocities of the $A_{0}$ and $S_{0}$ modes are consistent with those predicted by plate theories from structural mechanics. For the Kirchoff-Love plate theory, the velocity of the $A_{0}$ mode may be found from the equation decribing the flexural behaviour, as: v_{flexion}=\left( \frac{D}{\rho h} \right)^{1/4}\sqrt{\...
