Computer simulations of a 30 week pregnant small female were performed using a range of belt locations and impact velocities in order to evaluate a new injury predictor for the pregnant occupant. Frontal impact simulations with a range of velocities and belt positions were used to identify the best correlation between local uterine compression and peak strain measured at the uterine-placental interface. The results illustrate that local uterine compression correlates with peak uterine strain and is a better predictor then the overall global peak compression. It is critical for future pregnant dummy development and for overall protection of the pregnant occupant that injury criteria be evaluated. Abdominal compression is a simple measurement that should yield viable results when predicting the likelihood of injury to the fetus as a result of motor vehicle crashes.
