Results of experimental investigation and numerical modeling of high strain rate behavior of aluminium alloys AMg-6 and D-16 are presented. Using Split Hopkinson Pressure Bar (SHPB) parameters of Johnson-Cook's model and other models from LS-DYNA library were determined in strain rate range 102-104 s - 1. For verification of the models a comparison of the results of numerical modeling and model experiments was carried out. Modificated Taylor's test and modification of SHPB test for high-speed penetration were carried out as model experiments.
