Abstract:

The objectives of the proposed research are to 1 obtain a fundamental understanding of the effects of nano size aluminum particles on the constitutive and crack growth behavior of particulate composite materials, 2 investigate the effects of aluminum particle size on deformation mechanism, damage process, hysteresis, and fracture strength under a constant strain rate condition, 3 determine the role of interphase in damage initiation and evolution processes, 4 determine the deformation and failure mechanisms on meso and macro scales, 5 develop a micro structure and statistics based technology to evaluate the inherent material quality ,and 6 provide guidance for developing high strength nano solid propellants.
