AB - <p style="text-align: justify;">This paper deals with the numerical approximation of a pressure/displacement formulation of the elastoacoustic vibration problem in the axisymmetric case.
We propose and analyze a discretization based on Lagrangian finite elements in the
fluid and solid domains. We show that the scheme provides a correct approximation
of the spectrum and prove quasi-optimal error estimates. We report numerical results
to validate the proposed methodology for elastoacoustic vibrations.</p>
