The dangers of an explosive attack, and the evolving defensive measures to counter those attacks, have existed for centuries. Whether protecting people, facilities, or infrastructure, INL researchers take materials science to new levels. They design, develop, test, and manufacture armor solutions, conduct advanced modeling and simulation, perform data analysis, and detonate and analyze the blast effects of shaped charges, rockets, and improvised explosive devices. Our work creates informed solutions ranging from better barriers to stronger, lighter armor packages.

Materials and Armor Research

INL engineers and materials scientists are designing, validating, and manufacturing unique armor prototypes that increase protection while simultaneously reducing weight and production costs. Over the last 25 years, many of the lab’s armor designs have been used around the world to safeguard people, vehicles, and facilities.

INL manufactures the battle-proven armor for the U.S. Army’s Abrams battle tanks. We’ve designed and validated lightweight, bullet-trapping armor for law enforcement watercraft, outfitted remote weapons systems with large-caliber, ballistic-resistant protection, and hardened critical facilities to defend against explosively formed projectiles (EFP) and shaped-charges threats.

Capabilities

• Create custom armor applications with ceramic, metallic, and composite materials.
• Patent and license armor designs from material bonding and encapsulation research.
• Model armor designs using ABAQUS/ Explicit, LS-DYNA, CTH, ALEGRA, SHAMRC, and ALE-3D.
• Validate armor against explosive and ballistic threats like rocket-propelled grenades, EFPs, armor piercing, and fragment-simulating projectiles.
• Capture and analyze the interaction between penetrators and armor systems.
• Capture and record ballistic events up to 1 million frames per second with high-speed cameras.

INL has secure testing ranges where full–scale defense systems can be analyzed and tested under real–world conditions. The flexibility of the test range accommodates custom test setups for diverse development and testing campaigns.

INL’s test range capabilities are regularly utilized by DOE to gather data for vulnerability assessments and security plans. Security experts and materials researchers employ high-performance computing tools to simulate and predict explosive events using computational terminal ballistic models.

Since 1984, INL’s Specific Manufacturing Capability (SMC) has been the lead manufacturer of armor packages for the U.S. Army’s Abrams main battle tank. SMC has the ability to provide independent technical evaluations and solutions to manufacturing, engineering, and material science for a variety of programs and customers. SMC is designated as the Abrams Armor Center of Excellence.
