Conclusions

when bullet tries to penetrate into bucket or any object,the penetration purely depends on the bullet material,bucket material density and hardness.

both density and hardness will resist penetration,higher the density,hardness the penetration will be low.

we used three different materials for buckets depending on the density of the materials the penetration occured.
