dc.description.abstract | Systematic development of a new self-consolidating high-strength cementitious armor material, for use in protective construction against blast and ballistic impact, is presented. Multi-scale experimental methods are developed and implemented to optimize the material for quasi-static compression and flexure loading conditions, flow characteristics, interfacial bond between the matrix and high-strength steel fiber, and microstructure pore size distribution and porosity. The deviatoric and pressure-volume responses are characterized for the optimized material under quasi-static triaxial states of stress. A new pulse shaping technique is presented and utilized to satisfy stress equilibrium for constant high-strain rates on a large diameter Kolsky bar. The dynamic stress-strain responses are presented with the strength increase factors for the optimized cementitious armor. A series of ballistic experiments were undertaken to evaluate the performance of the new armor, with and without short fiber reinforcement, against fragmenting weapons and projectile impact. | |
