The Impact Physics group solves complex impact problems and has been conducting research and development for impact-resistant systems for government and industrial sponsors since 1965.


We have the most diversified indoor impact research facility in the world. Our 13 gun ranges are capable of propelling objects at velocities ranging from tens of feet per second to over 24,000 feet per second.


We routinely perform testing in the fields of foreign object damage (FOD), light armor design and evaluation, penetration mechanics, hypervelocity impact testing and analysis, and dynamic behavior of materials.



The breadth of topics studied by the UDRI Impact Physics group include:


Terminal Ballistics


Advanced armor development

Aircraft component survivability

Birdstrike testing

Foreign object damage

Fragment containment testing

Lightweight armor

Low-velocity impact damage

Military standard testing
