【Abstract】 In this paper, a model for the interaction of intense pulsed ion beams (IPIB) with metallic targets is briefly described. Then the thermal mechanical effects on the alumin um target irradiated by the IPIBs with ion energy of 300keV and 1.0MeV, current density of 10, 50, 100A/cm 2 are simulated numerically. The calculation results, i.e., the stress, temperature, t emperature gradient distributions, heating and cooling rates and elastic waves and shocks are presen ted and discussed.更多还原
