Comparisons of the simulation results with the experimental data [4] in terms of residual velocity for 12mm thick Weldox460E steel plates struck normally by conical-nosed projectiles. Figure 3. Comparisons of the simulation plot and the experimental image of 12mm thick Weldox460E steel plate after full perforation. Fig.4 shows comparisons of the simulation results and the experimental data obtained by Borvik et al. [12] in terms of residual velocity for 6mm and 16mm thick Weldox460E steel plates struck normally by flat-ended projectiles with diameter (20mm), mass (197g). Fig.5 shows comparisons of the simulation plot and the experimental image of the plate after full perforation.
