Research on the injury of blunt impact by non-lethal kinetic projectiles to the abdomen based on numerical simulation

Based on cadaver data on non-lethal kinetic projectiles impacting the human abdomen, the effectiveness of the THUMS AM50 Dummy Finite Element Model has been established. Using the Abdominal Injury Criterion (AIC) and Abdominal Peak Force (APF) to assess the abdominal injury, it has been determined that frontal impact of projectiles with a mass of 45g and velocity of 60m/s on the human abdomen results in a 50% probability of liver injury at the AIS2 lever or above. After comparing two different abdominal injury assessment criteria, it has been observed that the existing criteria show significantly different levels of adaptability under varying impact conditions.
