Abstract

Abstract: Free vibration analysis of doubly curved composite spherical shell panel is investigated using FEM. The frequency–amplitude relations for the free vibrated spherical shell are computed using eigenvalue formulation and are solved employing a direct iterative procedure using Ansys 12; two types of modeling are proposed: Shell99 and Shell281. Effects of moisture and temperature on the vibration characteristics of laminated composite shells are examined.
