3. Conclusion With the existing the two dimension Lagrange fluid dynamics code, we have added the cavity growth, polymerization and collapse effect of spallation processing function modes, and verify the model and program code through a numerical example. The damage evolution analysis of the unit near a single measuring point shows that the platform area in the velocity curve corresponds to the damage fracture zone in the metal. It is considered that the unit of the location has undergo the physical process of unload-stretching-damage-spallation-free flight- recompression.
