“…Roth thought that the Von Mises stress of brain tissue was a good predictor for moderate neurological windshield Shock tower location A injury of head [8]. The Von Mises stress of brain tissue decreased with the increase of skull stiffness under the impact loading (Table 1), which indicated that the head with softer skull was more prone to brain injury than that with stiffer skull.…”

Abstract. Skull stiffness of children is of great significance to protect brain tissues during traffic accidents. In this paper, the effects of skull stiffness on traumatic brain injury (TBI) are investigated by using a validated 6-year-old child head finite element (FE) model according to Chinese standard GB/T 24550-2009 Results showed that the HIC value, intracranial pressure, Von Mises stress and shear strain of brain tissue increased with the decrease of skull stiffness during the impact of FE model with engine hood. Therefore, the injury risk of the child head decreases with the increase of skull stiffness. And the skull with higher stiffness can provide a better protection for brain tissues during traffic accidents.

“…At a numerical level, lots of studies have dealt with the development of finite element models of human structures: head (Roth, et al, 2010), or shoulders (Duprey, et al, 2005) for example which can be coupled to human environment in order to improve its security. In developing "biofidelic models" research can be lead on injury mechanisms (Roth, et al, 2009) which can help to evaluate the dangerous behaviour of a structure (Meyer, et al, 2009). Finally, simulations have helped engineers to develop powerful models leading to an improvement of the life cycle for the design of a mechanical system.…”
