Three years old child neck FE modelling under automotive accident conditions

Despite of recent progresses in occupant safety, the protection of children is still not optimal. To offer a better understanding of child injury mechanisms, the present study proposes a human-like finite element (FE) model of a three-year-old child's neck. If model validation against scaled experiments involving adults is still under discussion it is today the only way to perform a validation of a child model. The developed neck FE model has been driven with dummy responses coming from experimental real world accident reconstruction using the Q3 dummy in the framework of the EU T-CHILD. A number of intra-cervical parameters have been computed and best correlation with the occurrence of injury was found to be the force transmitted to the odontoid.
