A single slice through the skull of a bat as seen in a micro-ct scan. Bone is white.|
3D surface model of the skull of the Jamaican fruit-eating bat (Artibeus jamaicensis).
This was imported into Strand7 as an STL file of triangulations.|
Strand7 FE model of the skull containing 251,968 tetrahedral elements.
Load vectors were applied to three nodes representing each of the two primary
jaw closing muscles: masseter and temporalis. Constraints were applied at the
three places where the lower jaw contacts and transfers forces to the skull
during feeding; the center of each jaw joint, and the tip of the tooth where
