Abstract

A dome resembles the hollow upper half of a sphere and has been used from the ancient times in building structures. It has inherent structural strength when properly built and can span large open spaces without interior supports. These domes can be subjected to missile and bullet attacks and can get damaged. Now a days many types of monolithic domes are being built to intercept missile attack. The damage depends upon the striking mass, its shape and velocity. The heavier the object and the faster it moves, the more damage it will cause. Also the shape of the striking object has an important role in piercing the target. An analytical study was planned on the bullet impact on different shapes of the domes. The speed attenuation was studied and reported. The effect of bullet nose shape and dome boundary conditions are also discussed.
