Biomechanical modelling of the human tongue
This project aims at building a 3D biomechanical model of the human tongue, including all the muscles which are embedded into tongue tissues. A non-linear hyperelastic Finite Element model has been built and inserted into geometrical models of the upper airways. This dynamical model is now used to study the complex speech production process. In the future, we plan to use it to assist the surgeries of tongue cancers, trying to give a prediction of the functional consequences of such surgical gestures.
