This paper presents a dynamic biomechanical model of the face. It is implemented with a finite element method in the ANSYS software environment. A three layered mesh adapted to the description of the complex face muscles' courses have been defined. Soft tissues are modelled using a hyperelastic law. The variations of muscle tissues' mechanical properties associated with muscle activation are functionally accounted for and their influence on facial mimics and movements are
