Abstract:
Traumatic brain injury (TBI) has long been known as one of the most anonymous reasons for death around the world. This phenomenon has been under study for many years and yet it remains a question due to physiological, geometrical and computational complexity. Due to limitation in experimental study on human head, the finite element human head model with precise geometric characteristics and mechanical properties is essential. In this study, the visco-hyperelastic parameters of bovine brain extracted from experimental data and finite element simulations which validated by experimental results. Then a 3D human head including brain, skull, and the meninges is modeled using CT-scan and MRI data of a 30-years old human. This model is named “Sharif University of Technology Head Trauma Model (SUTHTM)”. By validation SUTHTM, the model is then used to study the effect of G acceleration. Damage threshold based on consciousness in terms of acceleration and time duration is developed using HIC and Maximum Brain Pressure criteria
