The stress analysis of the human vocal fold
Original language description
A three-dimensional (3D) finite element (FE) fully parametric model of the human larynx was developed and used for numerical simulation of stresses during vibrating vocal folds the collisions. The complex model consists of the vocal folds, arytenoids, thyroid and cricoid cartilages. The vocal fold tissue is modelled as a three layered orthotropic material. The results of numerical simulation of the vocal folds oscillations excited by a prescribed intraglottal aerodynamic pressure are presented. The FE contact elements are used modelling the vocal folds collisions and the principal and shear stresses are computed in time domain on the surface and inside the vocal fold tissue. The results show significant dynamic stresses in all there directions and comparable maxima of Von Mises stresses were obtained for closed and open phases of the vocal folds motion.
