“…In Figure 6 From the previous data, the shell frequencies are affected highly as the fluid quantities [11,[31][32][33][34][35] and ring supports are appended [2,5,27,36]. A beam type vibration of CSs crops up when the addition of ring supports are made.…”

“…The ring support is composed for fluid-filled as 0 ≤ a ≤ L, for volume fraction law, the exponent p = 0. Here for C-I cylindrical shells, frequencies are some bit higher for those of C-II ones [32][33][34]. The effects of fluid-filled cylindrical shell with ring supports are perceived to be very conspicuous in the variation of natural frequencies.…”

“…A beam type vibration of CSs crops up when the addition of ring supports are made. [11,[32][33][34]. It is concluded that the maximum point and other relative value of C-II are bit smaller than that of corresponding value of C-I.…”

“…From Figure 5(a) and (b), it is observed that in both the cases, without fluid and with fluid for L=R and h=R, the value of ring support a = 0.3L which is sandwich between a = 0.5L, L. It is seen that the influences of ring supports and fluid terms are converse to each other. The ring supports increase the frequencies whereas the fluid loaded terms lower them [32][33][34].…”

Vibration analysis of fluid-filled functionally graded material (FGM) cylindrical shells (CSs) is investigated with ring supports. The shell problem is formulated by deriving strain and kinetic energies of a vibrating cylindrical shell (CS). The method of variations of Hamiltonian principle is utilized to change the shell integral problem into the differential equation (DE) expression. Three differential equations (DE) in three unknown for displacement functions form a system of partial differential equations (PDEs). The shells are restricted along the thickness direction by ring supports. The polynomial functions describe the influence of the ring supports and have the degree equal to the number of ring supports.
