High acceleration levels experienced by pregnant occupants in car crashesare the leading cause of foetal morbidity. The objective is to develop a FE model of a pregnant human body to investigate various crash scenarios and understand injury mechanisms involved. A 3D reconstruction of the foetus, placenta, and uterus wall (based on MRI images of a 50th-percentile woman) was performed. These geometries lead to a continuous mesh of the gravid uterus complex, then implemented in the Radioss Humos model. Frontal impact simulations were performed to record stress distribution on the fetus and to analyze kinematics of the uterus gravid. This model offers access to a first level of injury, and can be used to investigate better adapted security systems. For the covering abstract see ITRD E141569.
