Abstract

The aim of this research was to simulate a sever linear impact to the head and study the effect of impact on a brain substitute material in terms of deformations that generally lead to Traumatic Brain Injury (TBI). Simplified 2D models of transverse section of human brain were made with 5% gelatin as brain surrogate material. The models underwent 55G deceleration and the strain distribution was measured through image processing. Finite element (FE) models of the experiments were developed using Lagrangian formulations and validated. Using physical material properties, the FE computational parameters were determined based on the results of strain distribution and posterior gap generation. The strain and pressure levels in the FE model both reach the injury threshold levels known for brain tissue.
