Abstract: A 3D finite element (FE) fully parametric model of the human larynx was developed and used for numerical simulation of vocal folds vibrations excited by a prescribed intraglottal aerodynamic pressure. The complex model consists of the arytenoid, thyroid and cricoid cartilages. The vocal fold tissue is modelled as a three layered orthotropic material and the FE contact elements are used for modelling the vocal folds collisions. The principal and shear stresses on the surface the vocal fold tissue are computed in time domain.
Keywords: 3D FE model of human larynx; biomechanics of voice; numerical simulation of stress on vocal folds
