摘要：
Dynamic compressive behavior of aluminum alloy foams was analyzed using split Hopkinson pressure bar. Dynamic compressive stress-strain curves were obtained from the measured incident, transmitted and reflected waves from the given samples. It is found that the yield strength of the foam increases as strain rate increases and the compaction strain decreases with the increase of strain rate.
