Free vibration analysis of carbon nanotube reinforced composite shells

In this thesis, the free vibrations of various shaped shell structures are calculated and the effects of parameters on frequency is determined. Especially conical and cylindrical shells are examined and some examples are also solved as panel models. Shells are commonly used in avion-space, civil engineering and many more industries. According to terms of use, the free vibration frequency has a vital importance in sizing elements. The equations which are obtained in this thesis are solved by using Discrete Singular Convolution method (DSC), differential quadrature method and the finite element based computer program ANSYS. The obtained equations can be degraded into other forms shell or plate structures by arranging geometric parameters. By this way cylindrical shells, cylindrical panels and square plates can also be solved by arranging obtained equations if desired. Determining the effective parameters on frequencies is the main aim of this thesis.
