Abstract The dynamic properties of aluminium alloy foam were investigated by using split Hopkinson pressure bar (SHPB) with diameter of 40 mm. The aluminium
alloy pressure bar and pulse shape technique were used to modify the traditional
SHPB due to the low impedance of aluminium alloy foam. Wave dispersion correction on the aluminium alloy pressure bar was studied by Fourier series. And the
finite element numerical simulation was also performed to demonstrate and validate the dispersion correction results by Fourier series method. The reflected and
transmitted wave measured in SHPB experiments were corrected by the backward More >
