Abstract

A recently developed theoretical approximation, the reflected-afterflow virtual-source (RAVS) model, is applied to the case of a planar shock wave attacking an elastic cylindrical shell. Calculations are shown to be in good agreement with the exact calculations that were published by Huang for all locations and times. It is concluded that the RAVS model gives a good approximation for the loading and response of an elastic cylindrical shell attacked by planar waves. The RAVS model is shown to be even better for spherical waves that are of much more practical interest.
