Establishment of a head finite element model of craniocerebral trauma and model validation / 中国组织工程研究

ABSTRACT

This study established a finite element (FE) model of human body head (HBM-head) in accordance with human head anatomy.The anatomical structure of HBM-head was described in detail,primarily consisting of scalp,skull,dura mater,cerebrospinal fluid,pia mater,cerebrum,cerebellum,ventricle,brain stem,falx,and tentorium.The kinematic and kinetic responses,as well as the intracranial pressure distribution of the head model were compared with the data from the cadaveric impact tests to validate the head FE model.Experimental results confirmed that the head FE model had good biofidelity and could be used to study head-brain trauma in vehicle collisions and the underlying injury mechanisms.
