I want to know what are the best foam materials that can best absorb energy in compression. What is the highest registered value?
Can this be increased?
Hi;
I hope I can answer the question you have asked.
There are many varieties of foam materials. such as open or closed pore porous foam materials. ceramic or metallic foam material according to the type of material. metallic foam materials are among the most commonly used and preferred foam materials become Al-based foam material. Al alloying elements which affect the compressive strength in the foam material. Al also added into the ceramic particles (eg B4C, SiC, etc.) of the compression and impact strength of the metallic foam is increasing very significantly.
Dear Sadeem Fadhil,
can you tell the permissible deflection in absorbing the energy in compression?
Dear Halil
Thank you for your answer, I think the field needs an updating through a review that can go deep in collecting the best achievements in foam materials just like the amazing paper of Ashby
http://link.springer.com/article/10.1360/02yb0203
But, its a long interval of time from 2003 till now, please if any one knows any best achieved values on absorbing energy, will be grateful if s/he share these values with us.
Thank you
Dear Pramod Vadavkar
They usually calculate it till the densification strain of the material,
I suggest you reading the same above paper its worthy about the subject
Good luck
take a look at the following paper too:

You might find it useful.
I would like you to see the following paper, which has achieved the best specific energy absorption in compression for bulk materials:
