Abstract
This study focuses on vibration analysis of cylindrical pressure vessels
constructed by functionally graded carbon nanotube reinforced composites (FG-CNTRC).
The vessel is under internal pressure and surrounded by a Pasternak foundation. This
investigation was founded based on two-dimensional elastic analysis and used
Hamilton’s principle to drive the governing equations. The deformations and effectivemechanical properties of the reinforced structure were elicited from the first-order shear
theory (FSDT) and rule of mixture, respectively. The main goal of this study is to show
the effects of various design parameters such as boundary conditions, reinforcement
distribution, foundation parameters, and aspect ratio on the free vibration characteristics
of the structure.
