摘要：Results of a study on the perfom1ance of 10 rnrn low alloy, rolled-homogeneous armour (RHA)plate when impacted by 20 mm diameter steel ogive-shaped projectile at 15,30 and 45° angles ofattack in the subordnance velocity regime are presented. Experimental results show that 10 rnrn steelplate provides full protection at 45° obliquity up to a striking velocity of 530 rn/s. At low velocity(V < 350 rn/s), the plate provides protection at 30° obliquity, but fails to provide protection at an angleof attack of 15 0, even at low velocity ( V = 300 rn/s ).It is also observed that nom1al component of the strikiug velocity of the projectile is the main cause of plate perforation.
