Investigation of energy absorption capabilities of compressed and uncompressed crushable foams

Compressed and uncompressed crushable foam blocks were subjected to projectile impact at low velocity to evaluate and compare the foam resistance against the projectile impact. Among many crushable foam applications their energy absorbing characteristics play a prominent role to secure the structu...
