The Dynamics Effect and Material Parameters of Polyester Radiated by Electron Beam

The dynamics effect of polyester under electron beam radiation is studied. The energy deposition of electron beam in polyester is calculated by Monte Carlo methods. The thermal shock wave propagation and the blow off impulse of polyester are simulated by the hydrodynamic method. From the comparison between simulation and experimental results of blow off impulse and peak pressure of thermal shock, the obtained cohesive energy of polyester is about 1.1 kJ/g, and the value of Grneisen parmeter at standard state is about 0.2.
