Abstract
|
In this study, the free vibration of partially fluid-filled laminated composite circular
cylindrical shell with arbitrary boundary conditions has been investigated by using
Rayleigh-Ritz method. The analysis has been carried out with strain-displacement
relations based on Love’s thin shell theory and the contained fluid is assumed
irrotational, incompressible and inviscid. After determining the kinetic and potential
energies of fluid filled laminated composite shell, the eigenvalue problem has been
obtained by means of Rayleigh-Ritz method. To demonstrate the validity and accuracy
of the results, comparison has been made with the results of similar works for the
empty and partially fluid-filled shells. Finally, an extensive parameter study on a
typical composite tank is accomplished and some conclusions are drawn.
