Abstract

The dynamic compression behavior of porous carbon steels with cylindrical pores oriented in one direction was investigated. The application of dynamic compression parallel to the orientation of the pores at 77 K resulted in the formation of a plateau stress region, in which considerable impact energy is absorbed. The amount of energy absorbed is 10 times that of commercial aluminum foams. Plateau stress regions appear when crack propagation is suppressed, suggesting a starkly different mechanism from that of metal foams.
