10 An Investigation into the Dynamic Response of Vocal Folds
Download citation file:
In phonation process, the vocal folds collision during glottal closure is considered to be a risk factor for pathological development. This research is aimed at designing a dependable finite element (FE) model of the vocal folds for frequency and dynamics analysis and for calculating the impact stress on the vocal folds during glottal closure. A three-dimensional model with irregular geometry and a layered structure has been designed. The measured viscoelastic properties of the vocal-fold mucosa and the transverse isotropic elastic properties of the vocal fold muscle are applied in the model. The frequency and dynamic characters are presented using Abaqus™...
