Abstract
The effect of a proton beam, with proton energy of about 10 MeV, durat ion of 100 ns, and intensity of 5 - 10 GW/cm2, exerted on an aluminum target 1 mm thick is studied by the method of mathematical simulation in two-dimensional formulation. The evolution of a stressed state and die formation of the destruction zone and temperature fields for diffe rent values of beam focusings are investigated. The spallation strengt h of aluminum under given loading conditions is determined.
