Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.
