[100] Loading of Fcc Based Nanofibre Reinforced Composites

Abstract

Ab initio calculations of theoretical tensile and compressive strengths in the ⟨100⟩ direction of a composite having continuous nanobre reinforcements are performed using pseudopotential approach within density functional theory. Results for iridium or platinum nanobres in copper or gold matrices, presented as case studies, reveal that the theoretical tensile and compressive strengths almost linearly increase with increasing atomic concentration of the reinforcement exhibiting only slight positive strength deviations from the linearity for PtAu and slight negative deviations of the tensile strength for IrCu.
