Fifth International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2007)
A 3D biomechanical finite element model of
the face is presented. Muscles are represented by piecewise
uniaxial tension cable elements linking the
insertion points. Such insertion points are specific
entities differing from nodes of the finite element mesh,
which makes possible to change either the mesh or the
muscle implementation totally independently of each
other. Lip/teeth and upper lip/lower lip contacts are also
modeled. Simulations of smiling and of an Orbicularis
Oris activation are presented and interpreted. The
importance of a proper account of contacts and of an
accurate anatomical description is shown.
