Abstract: The governing equations of a two-layered circular cylindrical shell have been derived. A recently developed theoretical approximation, the reflected-afterflow-virtual-source (RAVS) model was applied to determine the fluid-structure interaction. Cases of two-layered infinitive length elastic cylindrical shell impinged by planar shock waves were investigated by using finite difference method. Results by using this model were compared to those by using the software USA/LSDYNA3D, and they are in good agreement. Some parametric studies were done to study the effect of the Young's modulus Ei and thickness hi of the structure on the transient responses of the shell. © 1998 Published by Elsevier Science Ltd.
