Dynamic Impact of High-Density Aluminum Foam

High-density aluminum foam can provide higher stiffness and absorb more energy during the impact Obtaining constitutive law of such requires tri-axial tests with very high pressure, where difficulty may arise because hydrostatic pressure reach than 30 MPa. In this paper, instead using tests, we proposed three easier tests—tension, compression shear to obtain parameters model (the Deshpande–Fleck model). To verify both statically dynamically, carried out additional triaxial direct respectively. Based on derived model, performed finite element simulation study response present foam. By dimensional analysis, an empirical equation for a non-dimensional time $${\bar{t}}_{\mathrm {d}}$$ , divided by required plastic wave travelling from surface bottom surface, determine deformation characteristic after impact. For case {d}}\le 1$$ tends exhibit shock-type characteristic, while {d}}>5$$ upsetting-type characteristic.
