Neck inury by rear-end collision occurs frequently in automobile accidents, yet its pathomechanical process has not been investigated. We performed impact analysis using finite element model, and a new neck model in rear-end collisions to investigate whiplash injuries in rear-end collisions. Compressive stresses localized in soft tissues, reached its maximum value at 140ms after collision at a speed of 5.7km/h. It is clear that the new neck model in rear-end collision behaves closer to that of human neck than the dummy neck.
