Multi-Scale Approach to Investigate the Tensile and Fracture Behavior of Nano Composite Materials

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.
