摘要：
Spall tests in pure copper and LY12 aluminum alloy are performed. Themechanism of the nucleation, growth and coalescence of micro-voids is observed bymeans of microscopic observation of the recovered specimens. The model presented inRef. [4] is incorporated in a hydrodynamic one-dimensional finite-difference computercode to simulate the processes of spallation in pure copper and LY12 aluminum alloyspecimens. This model can satisfactorily describe the processes of spallation.
