It is based on a displacement formulation for both the fluid and the solid. The pressure of the fluid is also used as a variable for the theoretical analysis yielding a well posed mixed linear eigenvalue problem. Lowest order triangular Raviart-Thomas elements are used for the fluid and classical piecewise linear elements for the solid. Transmission conditions at the fluid-solid interface are taken into account in a weak sense yielding a nonconforming discretization. The method does not present spurious or circulation modes for nonzero frequencies. Convergence is proved and error estimates independent of the acoustic speed are given. For incompressible fluids, a convenient equivalent stream function formulation and a post-process to compute the pressure are introduced.<\/p>","DOI":"10.1090\/s0025-5718-98-00901-6","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T22:13:45Z","timestamp":1027721625000},"page":"111-136","source":"Crossref","is-referenced-by-count":17,"title":["Finite element analysis of compressible and incompressible fluid-solid systems"],"prefix":"10.1090","volume":"67","author":[{"given":"Alfredo","family":"Berm\u00fadez","sequence":"first","affiliation":[]},{"given":"Ricardo","family":"Dur\u00e1n","sequence":"additional","affiliation":[]},{"given":"Rodolfo","family":"Rodr\u00edguez","sequence":"additional","affiliation":[]}],"member":"14","published-online":{"date-parts":[[1998]]},"reference":[{"issue":"4","key":"1","doi-asserted-by":"publisher","first-page":"1280","DOI":"10.1137\/0732059","article-title":"Finite element vibration analysis of fluid-solid systems without spurious modes","volume":"32","author":"Berm\u00fadez, A.","year":"1995","journal-title":"SIAM J.
