A systematic method of spall damage analysis was developed on the basis of damage mechanics. By use of a scalar damage variable, the damage evolution equation of Lemaitre et al. and the viscoplastic constitutive equation of Perzyna modified for the damaged materials were incorporated into the commercial finite-difference program MANJUSRI-3 D for nonlinear dynamic analysis. The process of spall damage and histories of stress wave propagation and temperature were analyzed for plate impact of OFHC copper disc targets. The results of analysis of the stress history and the particle velocity at the rear surface of the target plate were compared with those of the corresponding experiments.
