Finite element modeling of the human Brain Under impact conditions
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 6, Issue 6
Abstract
The head is the most vulnerable part of the body during crash situations and is often involved in life-threatening injuries. The main purpose of the present work is to build and validate a numerical model of human head in order to evaluate pressure and stress distributions in bones and brain tissues due to impact. Furthermore, the Head Injury Criterion (HIC) and the recently proposed Head Impact Power (HIP) criterion were evaluated with respect to the relative motion between the skull and the brain. It was found that the influence of impact direction had a substantial effect on the intracranial response. Geometrical characteristics for the finite element model have been extracted from CT and MRI scanner images, while material mechanical characteristics have been taken from literature. The analysis is performed using the program Ansys 3D to evaluate the risk of head injury in impact. The model is validated by comparing the numerical results and the experimental results obtained by Nahum in 1977.
