Traumatic injuries in accidents are measured using the Abbreviated Injury Scale (AIS), a risk to life scale. This project aims to study the injuries suffered by thoraco-abdominal organs during a crash and evaluate the subsequent AIS levels. Several injury mechanisms and criteria have been studied for the thoracic organs and strain-based metrics used for the evaluation of injuries. In the case of abdominal organs, a novel approach has been used in the creation of an Organ Trauma Model (OTM) based on Peak Virtual Power (PVP) method, an energy-based indicator, as it has a linear relationship with AIS. To validate the results, a real-life accident of a vehicle impacting against street furniture was simulated using a FEM software package, replicating the accident kinematics.
