The response of a hollow circular cylindrical shell of arbitrary thickness, in either an elastic or a viscoelastic medium, to transient dilatational and shear waves and their superposition is presented. The solution is valid within the scope of the linear theory of elasticity or viscoelasticity. The technique for obtaining the solution relies upon 1 the construction of a train of incident pulses from steady-state components, where each pulse represents the time history of the transient stresses in the incident wave, and 2 the existence of a physical mechanism that, between pulses, restores the disturbed particles of the cylinder and the surrounding medium to an unstrained state of rest. The influence on the cylinder response of the following factors is discussed linear thickness, cylinder-medium impedance mismatch, viscoelasticity in the medium, and incident wave form Step pulse, rectangular, triangular, linear rise-exponential decay.
