Correction factors are derived that show the effect of thickness on the fundamental resonant-frequency equations for cylindrical disks and rods and an equation is given that defines a boundary between a thick disk and a thick rod. These corrections are verified for isotropic and planar isotropic materials using the published frequency data of Shaw and McMahon. Direct comparisons are made with the correction factors of Moseley, Rayleigh, Onoe and Tiersten, Bancroft, and Baerwald. Experimental evidence is provided to show that upon substitution of appropriate frequency constants the corrections apply to the antiresonant frequencies of thick disks and thick rods.
