Abstract

The free vibration analysis of the sandwich complete conical shell with functionally graded materials (FGMs) facings based on the classical shell theory (CST) is studied. The basic equations of metal-rich truncated conical shells with FGMs facings are derived and solved by employing Galerkin method. The closed form solution for dimensionless frequency parameters of the sandwich complete conical shell with FGM facings is found. The effects of kinds of FGM facings and variation of thickness of facings on the magnitudes of dimensionless frequency parameters are studied in numerical analysis part.
