NDT Evaluation of Ballistically Impacted Laminar Composite Armor Steel.
Abstract
OAD-CARRYING CAPABILITY, BALLISTIC RESPONSE FOR BOTH BALL AND ARMOR-PIERCING PROJECTILES WAS EXAMINED WITH VARIOUS TENSILE LOADS THAT WERE APPLIED DURING IMPACT. Plates left intact after ballistic impact were tested in tension until failure. Residual strength values were subsequently determined. Prior to residual strength determination, the plates were magnetic-particle inspected. Ballistically induced crack formation was observed and analyzed. The influence of applied load during impact was determined. Subsequent residual strength values are interpreted in light of the crack formation revealed by magnetic particle inspection. Another ballistically induced defect is delamination that is produced between the hard and soft sides. It was found that the extent of delamination could be satisfactorily determined by ultrasonic C-scan pulse-echo technique. (Modified author abstract)
