Experimental results on the ballistic limits and failure mechanisms that lead to perforation in aluminum alloy target plates of 1-6 mm thickness by solid spherical projectile are presented. The projectile was launched between velocities of 150 m/s to 700 m/s by using the 10mm smooth bore gas gun. In this study, the attention was focused on the peculiarities of penetration process when the impact point approaches closely to the free or firmly fixed edge of the plate. The results were compared with the case of central impact and with others under changing the boundary condition, thickness and the target material properties.
