This report contains the results of ballistic testing of fabricated sections of Dual-Property Steel Armor DPSA. Specific items considered were bent, rolled, and extruded sections that simulated the geometry of close-fitting armor for critical aircraft components. Ballistic data for flat-plate sections were available prior to this program however, the data did not include the geometric or fabrication effects. The purpose of this program was to determine whether the ballistics armor characteristics changed as a result of fabrication. Within the range of the formed sections tested, no significant changes were noted in the ballistic properties of the material as a result of the forming operations.
