The Equivalence of Standard and Mixed Finite Element Methods in Applications to Elasto-Acoustic Interaction

Two commonly used problem formulations for the description of acoustic wave propagation are investigated; one is based on fluid displacement, and the other one is based on the velocity potential as the primary variable. Their equivalence under general Neumann boundary conditions is shown on both the...
