Abstract

In car accidents, components and restraint systems around the occupant can cause severe injuries to the abdomen area. Damage to the liver, the largest internal organ, can result in large amounts of bleeding, leading to fatal injuries. In this study, a liver model with internal blood vessels was developed and validated by dynamic compression ex vivo. Then, impact tests were conducted on a full-body human finite element model containing the liver. Finally, a side impact collision was simulated with the human model seated in the car, and liver deformation as well as internal injury caused by the blood were investigated.
