In this paper we solve an eigenvalue problem arising from the computation of the vibrations of a coupled system, incompressible uid -elastic structure, in absence of external forces. We use displacement variables for both the solid and the uid but the uid displacements are written as curls of a stre
## Abstract In this paper, we analyze the biharmonic eigenvalue problem by two nonconforming finite elements, __Q__ and __E Q__. We obtain full order convergence rate of the eigenvalue approximations for the biharmonic eigenvalue problem based on asymptotic error expansions for these two nonconform
