An apparatus for inhibiting effects of an explosive blast includes a central portion including a stiffening element and defining a radiused exterior surface and a plurality of sides extending from the central portion for attachment to a structure. The central portion and the plurality of sides are configured to redirect at least a portion of a blast wave resulting from an explosive blast. A vehicle hull includes a personnel compartment and an apparatus for inhibiting effects of an explosive blast operably associated with the personnel compartment. The apparatus includes a central portion including a stiffening element and defining a radiused exterior surface and a plurality of sides extending between the central portion and the personnel compartment. The central portion and the plurality of sides are configured to redirect at least a portion of a blast wave resulting from an explosive blast.

An armor includes a core that, in turn, includes a first layer of prismatic elements arranged in a tessellated fashion and a second layer of prismatic elements arranged in a tessellated fashion. The first layer of prismatic elements is nested into the second layer of prismatic elements. An armor includes a strike face sheet, a rear face sheet, and a core disposed between the strike face sheet and the rear face sheet. The core includes a first layer of prismatic elements arranged in a tessellated fashion, a second layer of prismatic elements arranged in a tessellated fashion, and a strain isolation layer. The first layer of prismatic elements is nested into the second layer of prismatic elements with the strain isolation layer disposed between the first layer of prismatic elements and the second layer of prismatic elements. The armor is at least one of curved in at least one direction, configured to include a corner, and configured to include a prismatic element of the first layer of prismatic elements or the second layer of prismatic element having a metallic layer disposed thereon.
