Abstract
This report investigates the possibility of improving Behind Armour Blunt Trauma (BABT) testing of hard ballistic protection in 3 ways. First, by replacing the cylindrical Blunt Trauma Thoracic Rig (BTTR) to a flat version (f-BTTR) so that boundary conditions of the hard plate be more representative. Second, by investigating the location and size of the point of contact of a typical hard ballistic plate on representative human thorax. Third, by investigating the possibility of using two 2-D laser scanners to determine the shape of the f-BTTR deformation during ballistic impact in 3 dimensions as a function of time. Those 3 improvements prove to be successful and will be used for further definition of a new BABT test method.
