Finite Element Analysis on Strains of Viscoelastic Human Skull and Duramater

Human skull and duramater has the viscoelasticity.Using the viscoelastic option of the ANSYS finite element program,this study analyzed the deformation of human skull and duramater with the changing ICP (Intracranial Pressure).The strains calculations were performed of three-dimensional finite element model of hollow shell simulating cranial cavity in this paper.The viscoelastic models for human skull and duramater were constructed.The result shows that the viscous strains account for about 40% and the elastic strains about 60% of total strains of human skull and duramater.
