ACCURATE FREE-VIBRATION ANALYSIS OF THE ORTHOTROPIC CANTILEVER PLATE

Utilizing the superposition method, an accurate analytical type soluti on is described for resolving the problem of free vibration of cantile ver plates with rectangular orthotropy. A number of verification check s performed to verify the mathematical procedure are described. Conver gence is found to be rapid and eigenvalues are tabulated for a wide ra nge of plate aspect ratios and a number of combinations of values of o rthotropic parameters. Full delineation is made between symmetric and antisymmetric modes. It is believed the tabulated results will prove u seful to designers and provide a reference against which other researc hers can compare their results.
