• Description:
  This report describes experiments in penetration mechanics on 6Al-4V titanium and 2024-T3 aluminum. This work was accomplished by the Lawrence Livermore National Laboratory (LLNL) at the LLNL Terminal Ballistics Laboratory of the Physics Directorate under an Interagency Agreement between the Federal Aviation Administration (FAA) William J. Hughes Technical Center and the Department of Energy (DOE). The work was accomplished under the FAA's Aircraft Catastrophic Failure Prevention Program as part of its research into the turbine engine uncontainment event. The object of the experiments was to determine the ballistic speed limit of 6Al-4V alloy titanium and 2024-T3 alloy aluminum and the failure modes of the projectiles and targets. Data was obtained for both materials using various thickness plates of the test materials to simulate aircraft skins and various size and shape 6Al-4V alloy titanium projectiles. The results of this experimental work will be used to help define the type of material failures in material models of the DYNA3D finite element code, which are being developed/validated for evaluating aircraft/engine designs relative to the federal airworthiness standards and for improving mitigation/containment technology.
