Resume — A muscle-driven model of human lower face was established. Three pairs of facial mimic muscles (ZM Zygomaticus Major, LLS Levator Labii Superioris, LAO Levator Anguli Oris), subcutaneous soft tissues, skin and skull were reconstructed based on segmentation of subject-specific MRI data. FE simulation were performed to reproduce designed facial mimic positions (e.g. pronunciation of soun...

Detailed finite element modeling of the human body offers a potential major enhancement to the prediction of injury risk during vehicle impacts. Currently, vehicle crash safety countermeasure development is based on a combination of testing with established anthropomorphic test devices (i.e., ATD or dummy) and a mixture of multi­ body (dummy) and finite element (vehicle) modeling. If a relative...

A new wavefield extrapolation method has been developed that allows the propagation of waves in an anisotropic medium. The anisotropic medium considered here is transversely isotropic (TI) with an axis of symmetry. Our method applies an asymmetric explicit correction filter after the normal isotropic extrapolation operator. It is stable and suitable for laterally varying TI media. This new sche...

INTRODUCTION Biot’s theory of poroelastic solids [1] describes the behavior of fluids in porous materials and provides the biophysical basis for loadinduced fluid flow in bone. Applying this theory to bone, compression of the matrix causes an instantaneous increase in pore pressure within the matrix; to equilibrate this pore pressure gradient, fluid moves out of the pore spaces of the matrix un...

Percolation phenomena play central roles in the eld of poroelasticity, where two distinct sets of percolating continua intertwine. A connected solid frame forms the basis of the elastic behavior of a poroelastic medium in the presence of external con ning forces, while connected pores permit a percolating uid (if present) to in uence the mechanical response of the system from within. The presen...
