چکیده مقاله:

This paper focuses on the free vibration analysis of thin isotropic oblate Spheroidal shells. The shell properties are assumed to vary continuously through the thickness direction. The analysis is performed following theFinite Element method used the finite element package ANSYS. This method as well as to estimate the natural frequencies and mode shapes for the shells. The obtained results it is found that increase the naturalfrequencies with increase the thickness of shell and at constant the thickness of base with varying thickness of head the natural frequencies increase
