Dear Mr. Noureddine,

You can find many works related to the performance of metal foams (MF) or Composite Metal Foams (CMF) armors against various threat sizes and impact energies. Depending on the CMF type, generally the larger the threat size, the more efficient the CMF armor.

Here you can find some of the interesting articles:
