| Abstract: | A new kind of numerical scheme for irradiation surface was proposed through Taylor series expansion.The propagation characteristics of thermal shock waves induced by soft and hard X-rays in c/ph were simulated with uniaxial strain elastic-plastic hydrodynamics model.The blow-off impulses in Ly-12 aluminum irradiated by intense pulsed X-ray were computed according to experimental time spectrum of X-ray source.The numerical results are in good agreement with the experiments. |
