Calculation of thermal-mechanical effects on the surface of metallic targets irradiated by intense pulsed ion beams

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 aluminum target irradiated by the IPIBs with ion energy of 300 keV and 1.0 MeV, current density of 10, 50, 100 A/cm2 are simulated numerically. The calculation results, i.e., the stress, temperature, temperature gradient distributions, heating and cooling rates and elastic waves and shocks are presented and discussed.
