The child model will be further validated and then used by safety researchers in the design of front ends of new vehicles in order to increase pedestrian protection of children. In addition, the most common injuries observed in pedestrian accidents including fractures of lower limb bones and ruptures of knee ligaments were predicted by the model.

The child pedestrian model showed also numerical stability under a typical CPC configuration. Overall, the results of the model showed a reasonable correlation to the test data in component validations. Component validations with simple impactor tests and a full-body validation in a car-to-pedestrian collision (CPC) were performed in LS-DYNA. The standing posture has been used as specified in the EuroNCAP testing protocol. Material properties were applied based upon previously published studies. The model was developed by morphing an existing GHBMC 5th percentile female pedestrian model to a 6-year old child geometry reported in literature. In this study, an advanced and computationally efficient finite element (FE) model corresponding to a six-year-old (6YO) pedestrian child was developed in LS-DYNA. Several pediatric pedestrian models have been developed but these existing models have several inherent limitations due to lack of biomaterial data. The development of a computational child model could be a better alternative that characterizes the whole-body response of vehicle–pedestrian interactions and assesses the pedestrian injuries. However, with exception of a child headform impact test, all other subsystem tests are designed for prediction of adult pedestrian injuries. In addition to adult pedestrian protection, child pedestrian protection continues to be an important issue in vehicle crash safety.

The main material, *MAT_PAPER, is an orthotropic elastoplastic model that supports both solid and shell elements. The main motivation for the models is to accurately simulate the production of food and beverage containers for the packaging industry. We here present two new material models for the modeling of paperboard materials.
