Abstract

In order to obtain approximate analytical solution of natural frequencies for the free vibration of anisotropic circular cylindrical shells made of GFRP (glass fiber-reinforced plastic) with simply supported boundary conditions, Love´s theory and Energy method are used. Computation results show that the fundamental frequency comes from different vibration modes while the winding angle varies, the effect of number of axial half waves is stronger than number of circumferential waves on natural frequency of free vibration of anisotropic circular cylindrical shell. The effect of shell´s geometrical parameters is also investigated on natural frequencies.
