Truncated conical shells have been extensively used in a wide range of engineering applications due
to their special geometric shapes, and their vibration properties have been interested by many researchers in recent
years. In this study, vibration analysis of truncated conical hollow shells constructed from the fiber reinforced
carbon/epoxy composites was investigated for different fiber orientation angles ([0o/90o], [15o/-75o], [30o/-60o], and
[45o/-45o]). Finite element analysis (FEA) was performed by using ABAQUS software for prediction of natural
frequencies and mode shapes within the extended frequency range. Natural frequency values were determined
for constant semi-vertex angle of the conical structure (45o), and boundary conditions of clamped-clamped
(C-C), simply supported-simply supported (S-S) and clamped-free (C-F). It is concluded that natural frequency has
been significantly affected by boundary conditions while it has been little effected by fiber orientation angle those
effecting on mode shapes associated with natural frequencies.
