Analysis of the Mechanism of Lateral Impact Aortic Isthmus Disruption in Real-Life Motor Vehicle Crashes Using a Computer-Based Finite Element Numeric Model: With Simulation of Prevention Strategies

Abstract

Simulation supports the lever hypothesis that the force on the short-arm aortic isthmus is proportionally greater than at the long-arm proximal aorta. Simulation also suggests improved vehicle construction techniques, which increase the strength and resistance to deformation of the B-pillar and vehicle side structure plus a B-pillar airbag will limit the intrusion forces causing LMVC AIs and reduce the incidence of associated head injuries.
