In this paper, head impact simulations subjected to high accelerations were conducted. HIC (Head Injury Criteria) known as one of the most popular evaluation index for a head injury, WSTC (Wayne State Tolerance Curve) and JHTC (Japan Head Tolerance Curve) have been proposed based on limitations of the cerebral concussion. However, they are empirical indices and the relation between the damage of the brain tissue and these indices have not been clarified well. So we calculated the dynamic behaviors of a human head subject to impact accelerations and investigated the relationship between the stresses in the brain stem area, which is considered to be the center of consciousness and several head tolerance curves. The obtained results represented the stress time integration value at the brain stem area is almost constant in any calculated point on JHTC.
