Human body Finite element models have the potential to provide significant insight into the paediatric response to impact. However, child models are by far less common and less advanced than their adult counterpart. The aim of the current study is to report on the development of a new child model (PIPER Child model) that aims to be continuously scalable between at least 1.5 and 6 years of age. After an overview of the model composition for all anatomical regions, examples of simulations performed for its validation are provided for all regions to illustrate the model performance. The scaling methodology used to account for the changes of model dimensions with age is also summarised along with the tool developed to apply the changes (PIPER tools). Short term perspectives include the completion of the validation simulation and the refinement of the scaling procedures to include the effects of age on material parameters, and to develop the capability to scale the model to any external anthropometry target. The model, along with all validation simulations and associated tool will be released under an Open Source license in April 2017.
