Development of an Improved Ballistic Acceptance Test for High Hard Armor Steel

摘要

This report is one of three reports generated as a subtask under the projectentitled 'Development of Improved High Hard Armor Steel MIL-A-46100)' funded by the PM, Survivability (TACOM). This report investigates ballistic acceptance tests for MIL-A-46100 plate. Ballistic test results for MIL-A-46100 armor plate with the 20mm M602 projectile show a high level of scatter in V50 values. The V50 is used as the criterion for acceptance/ rejection of MIL-A-46100 armor plate. Furthermore, the M602 projectile produces a shatter gap phenomenon when tested-verses high hardness plate near the 1.1 inch thickness. The shatter gap results
