This paper presents an analysis of submerged orthotropic cylindrical shells subjected to underwater shock wave. The equations of motion of orthotropic circular cylindrical shells are used in conjunction wtih the Reflected-Afterflow-Virtual-Sour (RAVS) model to model the fluid-structure interaction. The finite difference method is then employed to solve the governing equation for the problem of the infinitive length orthotropic cylindrical shell subjected to planar shock waves. A comparison of the results respectively obtained by present analysis and USA/LSDYNA3D code is made to verify the present solution. By using the present approach, the effects of orientation α, thickness-radius ratio h/R and curvature I/R on the transient responses of the shell are examined.
