Rock art compels interest from both researchers and a broader public, inspiring many hypotheses about its cultural origin and meaning, but it is notoriously difficult to date numerically. Barrier Canyon-style (BCS) pictographs of the Colorado Plateau

A cooperative test program to assess the oxygen compatibility of aluminum-lithium alloys with NASA White Sands Test Facility (WSTF), NASA Marshall Space Flight Center (MSFC), and the National Institute of Standards and Technology (NIST) led to the as

In mechanical-impact tests, the potential energy of the plummet is divided between energy absorbed by the specimen, the plummet's kinetic energy of rebound, and various losses in the test machine. Thus, all of the potential (or drop height) energy is

In mechanical-impact testing of Al-Li alloys and Al alloy 2219 for oxygen compatibility, specimens absorb a significant amount of energy in a short time. The absorbed energy is sufficient to crack and, in many cases, produce large fractures (splits)

Open-cup and pressurized mechanical-impact tests have been conducted at the NASA White Sands Test Facility (WSTF) on selected tempers of Al-Li alloys (2090, 8090, WL049), and A1 alloy 2219. Both liquid (LOX) and gaseous (GOX) oxygen environments were
