Human Skull Meshing & Analysis from Scanned Geometric Data
Wilde generated meshes from a scanned human skull and assessed the stress distribution in the occipital bone to assist research at Royal College of Surgeons in Ireland. Actual skull geometry was obtained from a CT scan and transformed into an STL format.
ANSYS ICEM-CFD meshinbg technology was used to clean up the STL file and mesh. As the meshing is patch independent, appropriate mesh densities could be specified without being constrained by the resolution of STL description. Suitable pressure boundary conditions were applied based on weight and centre of gravity of a typical human head.
From a static structural analysis, total displacements and von-Mises stress results were obtained.
The peak stress of 6.3MPa was predicted to occur between the occipital condyle and foramen magnum. The maximum displacement of 0.28mm occurred at the tip of the occipital bone.
