Abstract
This study is to review the Brain Injury Criterion (BrIC) and the brain injury probabilities due to the Traumatic Brain Injury (TBI). For this purpose, the frontal impact test results of 20 vehicles from MY2022 and MY2023 USNCAP are utilized for estimating the BrIC and the brain injury probabilities. Using the equations suggested by Takhounts et al., the BrIC results were calculated. Using the equations suggested by Hazay et al., the brain injury probabilities were estimated. The brain injury probabilities based on the maximum principal strain (MPS) were largely estimated than those based on the cumulative strain damage measure (CSDM).
