Non-linear dynamic analysis of anisotropic cylindrical shells a containing a flowing fluid
An analytical model is presented to predict the influence of nonlinearities associated with fluid flow on the dynamic behaviour of a structure consisting of shells and a surrounding fluid medium. The model requires the use of two linear operators to control the equilibrium of the shell and the velocity potential, a linear boundary condition of impermeability and a nonlinear dynamic boundary condition. The method is based on thin shell theory and the non-rotational flow of nonviscous fluids, in combination with finite element analysis.
