While it is clear that the models\u2019 responses are sensitive to geometry, it is not clear how and to what extent specific geometric features influence model motion. In this study geometric features that played significant roles in governing the motion of a two-layer (body-cover), two-dimensional, finite element vocal fold model were identified. The model was defined using a flow solver based on the viscous, unsteady, Navier\u2013Stokes equations and a solid solver that allowed for large strain and deformation. A screening-type design-of-experiments approach was used to identify the relative importance of 13 geometric parameters. Five output measures were analyzed to assess the magnitude of each geometric parameter\u2019s effect on the model\u2019s motion. The measures related to frequency, glottal width, flow rate, intraglottal angle, and intraglottal phase delay. The most significant geometric parameters were those associated with the cover\u2014primarily the pre-phonatory intraglottal angle\u2014as well as the body inferior angle. Some models exhibited evidence of improved model motion, including mucosal wave-like motion and alternating convergent-divergent glottal profiles, although further improvements are still needed to more closely mimic human vocal fold motion.<\/jats:p>","DOI":"10.1121\/1.3557046","type":"journal-article","created":{"date-parts":[[2011,4,9]],"date-time":"2011-04-09T00:58:02Z","timestamp":1302310682000},"page":"2121-2132","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":23,"title":["Identification of geometric parameters influencing the flow-induced vibration of a two-layer self-oscillating computational vocal fold model"],"prefix":"10.1121","volume":"129","author":[{"given":"Brian A.","family":"Pickup","sequence":"first","affiliation":[{"name":"Brigham Young University Department of Mechanical Engineering, , Provo, Utah 84602"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott L.","family":"Thomson","sequence":"additional","affiliation":[{"name":"Brigham Young University Department of Mechanical Engineering, , Provo, Utah 84602"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2011,4,8]]},"reference":[{"key":"2023073102105845000_c1","first-page":"35","article-title":"ADINA Theory and Modeling Guide Vol. III: ADINA CFD & FSI","author":"ADINA","year":"2009"},{"key":"2023073102105845000_c2","doi-asserted-by":"publisher","first-page":"97","DOI":"10.1016\/S0892-1997(03)00012-2","article-title":"The false vocal folds: Shape and size in frontal view during phonation based on laminagraphic tracings","volume":"17","year":"2003","journal-title":"J.
