✦ Synopsis

This paper presents a theoretical analysis of the axisymmetric response of an infinitely long, circular, cylindrical shell which is filled with a compressible fluid medium and is subjected to a ring load traveling axially at a constant speed. The solution is derived by using shell theory, which includes the effects of rotary inertia and shear deformations. Numerical results are presented for the case of steel shells filled with water. The first critical speed is compared with that for an empty shell. Further, the radial displacement and the bending moment of the shell are plotted as functions of the axial variable for several values of the load speed and the thickness-to-radius ratio of the shell. The response curves are compared with those of empty shells. From the results it is observed that the effect of an internal fluid medium on the response of the shell becomes more significant as the speed of the load becomes higher. The numerical results are also compared with those from elemen-tat3' shell theory.
