Estimation of the Thermal Shock Wave and Spall of Aluminum Alloy Irradiated by an Electron Beam

In this paper, we estimate the thermal shock wave and spall effect of LY-12 aluminum exposed to a high-current and low-energy relativistic electron beam. Melting process must be adequately taken into accounted for the material dynamic response calculation in the intermediate energy deposition range. The equation-of-state (EOS) used is GRAY three-phase EOS, which gives a more detailed and complete thermodynamical description of metals in the melting range. The calculated results are basically consistent with the experimental results.
