Abstract
The design and development of the EUROSID thorax is presented here. The chest, which was based on the concept of the aprod chest, and the development of a new shoulder is described. The degree to which the performance of these parts matches cadaver results is shown. Shown is that a thorax has been produced, that can measure chest deflection, the injury parameter preferred by the ad- hoc group. It can also measure the more recently proposed criteria such as the viscous injury criteria.
