| Abstract: | We have made numerical simulations of the propagation of thermal shock waves induced in aluminum alloys irradiated by the electron beam on "FLASH-Ⅱ", adopting an analytic method of the energy deposition, the constitution relation of material in low-pressure zone and one-dimension strain model of the elastic-plastic hydrodynamics. The computed results show that the computed values are in basically agreement with the measured. |

| Keywords: | electron beam thermal shock wave energy deposition numerical simulation. |
