As the threat of terrorist attacks or explosive accidents increases, interest in design and construction of blast resistant structures has increased. Recently, the blast reinforcement for existing buildings which were not designed to resist blast loading has been issued, and the demands for blast protective materials are continually growing. This study investigates the analytical study for evaluating impact resistance capacity and failure mode of PROTECT (Poly Resilience-Oriented hybrid TEChnology plaTe) panel. PROTECT panel is a composite panel with two steel plates and nano-composite. Since it is a multi-layer structure, there are advantages for the blast resistance. The impact resistance analysis of PROTECT panel is performed with the impact energy, the thickness of the steel plates and nano-composite as variables. In order to perform impact analysis, dynamic properties of steels and nano-composite were determined. Finite element analysis is performed with these properties under the drop-weight impact. From the finite element analysis, different failure modes corresponding to different impact energy is derived.
