SwRI Engineering Dynamics Department staff members analyze the explosive effects of bare and cased charges including structural breakup, debris throw, air blast, and scaling.

Accidental explosions and deliberate bombings by criminals and terrorists cause extensive structural and property damage, personal injury, and loss of life. Southwest Research Institute (SwRI) provides practical solutions to problems associated with:

  • Blast effects
  • Fragmentation
  • Penetration
  • Protection

Our Engineering Dynamics Department offers a unique blend of experimental, analytical, and numerical expertise that permits a multifaceted approach to solving safety problems.

Ballistics and Explosives Range

SwRI operates and maintains the Ballistics and Explosives Range on the San Antonio campus. This 10-acre facility permits a wide variety of experimental programs to be conducted, including:

  • Explosive loading
  • Hazards evaluation and mitigation
  • Foreign object damage
  • Ballistic impact
  • Armor testing
  • Hypervelocity impact

SwRI technicians provide expert support for handling explosives, firing gas and powder guns, and collecting high-rate electronic data. A complement of equipment, including an on-site machine shop, digital data acquisition and transient recorders, high-speed imaging equipment, and data processors, supports range activities.
