Constitutive Characterization of Multi-Constituent Particulate Composites
Abstract
Multi-constituent epoxy-based particulate composites consisting of individual particles of aluminum and a second phase (copper, nickel or tungsten) have been synthesized. The mechanical and physical properties of the composite depend on the mechanical and physical properties of the individual components; their loading density; the shape and size of the particles; the interfacial adhesion; residual stresses; and matrix porosity. These multi-phase particulate composites have been generated to investigate the deformation of aluminum in the presence of the second phase. Quasi-static and dynamic compression experiments have been performed to characterize the materials. The microstructures of the quasi-statically and dynamically deformed samples have been quantified to determine the amount of deformation in the aluminum particles, as a function of their proximity (i.e. near or far) from the second phase particles.
