The honeycomb structure shape and size have significant effect on its structural characteristics. The objective of current research is to evaluate the structural response of honeycomb structure under impact loading conditions using techniques of Finite Element Analysis. The impact analysis of honeycomb structure is conducted using ANSYS explicit dynamics. The equivalent stress distribution varies with impact velocity of the bullet. The maximum equivalent stress is obtained at the inner center region of honeycomb structure. The honeycomb structure enables to reduce the velocity of bullet significantly.
