✦ Synopsis

This paper presents a theoretical analysis of a dynamic boundary value problem of a finite length, homogeneous, isotropic, linearly elastic, cylindrical shell. The shell is subject to time-dependent surface tractions and/or time-dependent boundary conditions. Formal solutions have been derived by using the classical method of eigenfunction expansion combined with the modal acceleration method to treat the time-dependent boundary conditions. A numerical example of the transient response of a hollow cylinder subject to a longitudinal impact is worked out to study the influence of the transverse normal strain and for comparison with the results of the thin shell theory. The results indicate that the effect of the transverse normal strain is quite significant for the specific example under consideration. The dynamic response of the longitudinal impact of the hollow cylinder may have practical implications.
