The American Society of Mechanical Engineers (ASME) will name the Split-Hopkinson Pressure Bar Apparatus a Historic Mechanical Engineering Landmark, a status accorded mechanical systems and devices that contribute to the progress of mechanical engineering technology.

Developed at the Southwest Research Institute in 1962, the Split-Hopkinson Pressure Bar Apparatus helps test the dynamic strength of materials ranging from metal and steel to today's advanced polymers and ceramics. In one instance, NASA used it to evaluate the capability of the pressurized hulls of the U.S. Space Station to withstand the impact of meteorites and other flying orbital debris. The instrument works using compressed gas to launch a test-striker and records the data electronically.
