Undamped vibration of fibre-reinforced polymer overwrapped pipes under fluid-hammer conditions

AN APPROXIMATE DYNAMIC MODEL describing the undamped radial vibration of thin-walled steel pipes with an overwrap of laminated fibre-reinforced polymer (FRP), due to fluid-hammer conditions, is derived. The derived model is an uncoupled model, in which the elastic properties of the pipe and fluid are used to estimate the properties of the fluid-hammer-induced pressure wave. This pressure wave is used as the exciting load in a dynamic analysis of the pipe wall. The derived governing equation is solved analytically by utilizing the properties of Fourier series. The model is implemented on a representative example. It is observed that increasing the number of FRP laminae may lead to larger radial deflections, because the natural frequency of the pipe is significantly altered.
