The qualities of the prediction of the Thoracic Trauma Index (TTI) and the Viscous Criterion (VC) for the torso injury severity according to Abbreviated Injury Scale (AIS) are tested in the 90-degree car to car lateral collision, and impact of the left torso against a rigid or a padded wall. Forty-two restrained human corpes in the age range of 18 to 65 years, located at the near-side front passenger seat were used. The impact velocity amounted 40 to 60 km/h. In the second group tested, the left side of the test subjects were impacted under one of two different test conditions: 24 km/h rigid wall and 32 km/h padded wall. The thorax deformation has been evaluated by a double integration of the acceleration integration of the acceleration difference at the 4th and 8th rib, near-side and far-side. The statistical analysis showed a stronger influence of the age among the test conditions regarding the injury severity than the loading criteria in the investigated collective. The TTI shows the highest correlation with thorax AIS and the number of rib fractures. VC is more suitable to predict abdomen AIS severity. (A)
