Axisymmetric Free Vibration of Layered Cylindrical Shell Filled with Fluid

Abstract The aim of the study is to analyse axisymmetric free vibration layered cylindrical shells filled with a quiescent fluid. fluid assumed be incompressible and inviscid. equations vibrations shell fluid, on longitudinal transverse displacement components are obtained using Love’s first approximation theory. solutions functions in separable form obtain system coupled differential terms functions. approximated by Bickley-type splines. A generalized eigenvalue problem solved numerically for frequency parameter an associated eigenvector spline coefficients. Two three different types materials under clamped-clamped boundary conditions considered. Parametric studies made variation respect length-to-radius ratio length-to-thickness ratio.
