Abstract

A micromechanics and load transfer model is presented to examine how the alignment of nano-inclusions within nanocomposites affects the overall energy storage and dissipation capacity. A model based on principles from an extended Cox model for discontinuous fiber reinforcement and generalized shear lag analysis for off-aligned discontinuous fibers is presented. The model accounts for interfacial shear stress variations along the azimuthal direction of the inclusion surface that are a result of non-zero alignment angles with respect to the applied loading. The results demonstrate that the loading alignment angle can substantially affect the interfacial damping.
