Effect of composite laminated layup on vibrational behavior of composite pipe containing flowing fluid

In this study, the effects of composite laminated layups on vibrational behavior of fiber reinforced composite pipes containing flowing fluid have been studied. Composite layers layups can be in different arrangements and each layup affects the natural frequency of composite pipe containing fluid. The orthotropic layup, angle of composite layers and symmetric layup have been theoretically investigated. The governing equations have been solved with Mode Summation and State Space method. Proper composite laminated layup for obtaining optimum natural frequency has been recommended. Using ANSYS software, Finite Element Method Analysis has been applied and the results were compared with theoretical analysis.
