Abstract

A fully hierarchical finite elements code for solving coupled elasto-poro-acoustic problems was presented. The performance of hierarchical elements was compared to linear elements for dynamic problems. The performance was demonstrated for a plate backed by a rigid cavity. The thickness of the plate was 3 mm and the thickness of the cavity was 0.35 m. Results showed that the order of approximation per unit length in the hierarchical code was 33 for the plate and 12.5 for the cavity.
