    Abstract
  • The spallation experiments of Al-Li alloy have been carried out and the free surface velocity temporal curves for the spallation events have been measured. Based on the microscopics statistics and phenomenological analysis, a damage evolution equation is developed, which involves the effects of the growth and nucleation of microcavities as well as the effects of the material's compressibility. Inserting the constitutive equation and Murnagham state equation of Al-Li alloy and the damage evolution equation into ANWP, which is a special program for one-dimension strain wave, and by the numerical simulation of the free-surface velocity temporal curve for the spallation events in the gas gun experiments, we have obtained the related parameters in the damage evolution equation and the spallation criterion.
