Abstract

In this study a new three-dimensional human head finite element model (FEM), the WSU Brain Injury Model, representing a 50th percentile male human head, was used to study brain response to rotational impacts. An angular acceleration pulse taken from J.M. Abel's monkey test data (1978) was scaled to study human brain response. The scaling method used maintained approximately equal shear strain level in the brain and equal displacement of the head. Viscoelastic responses of the brain to impulsive sagittal and lateral rotational accelerations were obtained. Differences in brain response between sagittal and lateral rotational impact were found. The influence of the brain material properties on model response was investigated.
