Enhancement of quasi-static compression strength for aluminum closed cell foam blocks shielded by aluminum tubes.

Aluminum closed cell foam blocks are created with a volume of 1 inch which consist of aluminum foam parts shielded with part of aluminum tube and in some types reinforced with inner aluminum tubes. Blocks have been made to overcome some existing problems in metallic foam used to protect some applications parts from impacts as a sacrificial part. Metallic foam has three main categories sandwich panels, filled tubes and corrugated sheets.
