Abstract :
In order to investigate the effect of winding angle of fiberglass on the parametric vibration of cylindrical anisotropic shells considering viscosity, the Mathieu Equation is derived from dynamic equilibrium equations while some assumption are taken. Using method of small parameter, the first unstable region of the Mathieu Equation is determined. The effect of winding angle of fiberglass on the material damping is also investigated. The results suggest that with increasing damping, the un-stable region increases. But damping can not prevent response from increasing infinitely in the un-stable region.
