Work in Progress on LLNL's EOS for Metals including Beryllium

We are currently working on updating a number of Equation of State (EOS) tables that have been developed at Lawrence Livermore National Laboratory (LLNL) over 2 decades ago. Some of these EOS tables are still routinely used in hydro-code calculations such as Be EOS for simulating Be capsules in NIF experiments. Over the past decade, much progress has been made toward a better understanding of EOS properties. Experimentally, both static and dynamic high-pressure physics experiments have been carried out to obtain measurements at higher pressure regions. Theoretically, many first principles density functional theory (DFT) and molecular dynamics simulations have been applied to our materials of interest. We aimed to develop multiphase EOSs that would incorporate current experimental data and use the most up-to-date theory where data is not available.
