Welding and Explosive Bonding of a High Hardness Armor Steel: A Mechanical and Ballistic Property Evaluation.
Abstract
This effort is concerned with the mechanical and ballistic behavior of both butt and corner weldments of air-melted laminar composite armor steel. Weld filler metal composition for these weldments is given. The baseline strength properties are presented and compared with baseline mechanical properties of unwelded material. Extent of ballistic damage as a result of impact with .30 cal. ball and AP projectiles is obtained in terms of maximum lateral damage (MLD) defined as the maximum amount of damage measured transverse to the loading direction. Residual strength of ballistically damaged specimens is obtained and analyzed in terms of MLD. An additional joining technique that could simplify the construction of structural attachments is also discussed. This technique is explosive bonding of aluminum to the high hardness armor steel. Mechanical and ballistic behavior of explosively bonded composite are evaluated.
