A test campaign using Al6061-T6 targets was completed and HEL, spall stress, and equation of state parameters were measured. These results can be directly compared with full-size conventional plate-impact tests performed in 2014 by Southwest Research Institute on a cast version of the same material. Results overall compare well confirming that the laser-driven technique could, in some cases, replace the full-size test and be much more cost effective.
This presentation will summarize the effort by first describing the system as built at the SwRI facility and showing examples of the signals obtained when testing the Al6061. The last part of the presentation will be dedicated to compare results from laser-driven technique and the conventional plate-impact technique.
