| Abstract: | A human brain 3D finite element model,base on the human brain CT scan image,is proposed,where the material elasticity and viscoelasticity are considered to characterize the material feature.A commercially available software PAM-CRASH is chosen for model analysis,the time history of head acceleration and stress are regaded as model responses.The brain stress contours are also obtained from the impact simulation of the finite element model to draw the conclusions. |
