Abstract
In the current proposal, the bone-foramen biological designs will be utilized to develop a shock mitigation material system that attenuates the ballistic response to the industry standard tolerance level. The proposed material system will be capable of mitigating detrimental high frequency shocks for equipment and reducing fatal low frequency load transmission for occupants. A bone-foramen inspired material system consists of basic materials which will be basic metallic foams with different densities. The density distribution pattern is governed by the bone-foramen material distribution pattern. LS-DYNA will be employed to capture the ballistic response-mitigation behavior. The M4 Engineering in-house optimization package will be applied to the optimization of the bone-foramen inspired material system for best ballistic response-mitigation behavior. High strain rate compressive and indentation tests using split Hopkinson pressure bar (SHPB) will be conducted to establish and verify the material properties for constitutive model in LS-DYNA. MIL-STD-810F Large Scale Ballistic Shock Simulator (LSBSS) and Drop Table experiments will be performed to quantify the mitigation of ballistic response on the optimized bone-foramen inspired material system.
