hammer that is swung into a notched square/rectangular section specimen bridged across a set of “anvils” positioned in the hammer path. This gives rise to specimen strain rates in the region of 10-1 to 100-1, with resultant impact energies of up to 600J. Drop Weight Impact testing machines employ...
