Résumé

The analysis of the hydrodynamic fields induced in cylindrical shells by an external shock loading is presented. The model of irrotational, inviscid, and linearly compressible fluid is used, and the shell is assumed to be thin enough for the linear theory of shells to apply. The fluids and the shell are coupled through the dynamic boundary condition on the interface. The finite difference technique was employed to obtain the harmonics of the shell displacements. The simulated images based on the solution developed were compared to the available experimental ones for some of the pressure components. It was observed that the dynamics of the acoustic field when the fluids are identical.
