Abstract
This report describes some full-scale controlled impact experiments in which cars were driven head-on into the face of a massive concrete barrier. The purpose of these experiments and other similar tests is to obtain information on the forces arising in collisions, the nature and extent of the deformation of the car structure, the deceleration pattern of the passenger compartment and the motion of the bodies of anthropometric dummies carried in the cars, and to collect data needed in the design of seat belts and their anchorage points. The results described in this report relate to three cars of make one but different design.
