| Abstract: | Objective To establish a human 3D finite element skull model,and to explore its value in biomechanics analysis.Methods The cadaveric head was scanned and then 3D skull model was created using Mimics software based on 2D CT axial images.The 3D skull model was optimized by preprocessor along with creation of the surface and volume meshes.The stress changes,after the head was struck by an object or the head hit the ground directly,were analyzed using ANSYS software.Results The original 3D skull model showed a ... |
