The penetration mechanics staff is internationally recognized for contributions to fundamental and applied understanding of the mechanics and physics of penetration.
High-speed diagnostics and a wide variety of launchers are used to support experimental studies. Demonstrated capabilities include sabot design and fabrication for a wide range of projectiles from irregular-shaped objects to long rods with high aspect ratios (L/D < 30). A complementary high-rate materials laboratory enables material characterization and determination of computational constitutive constants.
