Abstract
A series of impact tests of sandwich samples were completed using a large-diameter split Hopkinson pressure bar (SHPB) device at different velocities. The interlayer is made of foam concrete, loess or sand. The stress peak value decay, energy decay and waveform dispersion characters are studied by comparing incident waves with transmission waves. The tests indicate that the foam concrete has the best capabilities of shock resistance and energy absorption, the loess comes second, and the sand takes third place.
