Undamped Vibration of Laminated Fiber Reinforced Polymer Pipes in Water Hammer Conditions

Abstract

A dynamic model for undamped, water hammerinduced, radial vibration of long, thinwalled, laminated, filament wound pipes is derived. The model is based on the interaction of the unsteady flow parameters with the anisotropic elastic properties of the pipe. With the aid of integral transforms and generalized functions, an approximate solution of the derived governing equation is achieved and its implementation on a representative example is discussed.
