A comparative study of the elasto-plastic properties for ceramic nanocomposites filled by graphene or graphene oxide nanoplates

Abstract As nanoscale reinforcements, the graphene and oxide nanoplates exhibit distinct mechanical physical properties. The determination of effective elasto-plastic behavior nanoplate/ceramic nanocomposites different filling effects nanoplate deserve systematic investigation. In this work, we intend to uncover how affect macroscopic characteristics ceramic matrix what differences in both enhancements. A homogenization model is first utilized for determining elastic parameters composite with a perfect interface. Then slightly weakened interface introduced characterize sliding matrix, such filled composites incorporating interfacial are explicitly formulated. Furthermore, nonlinear micromechanics developed investigate elastoplasticity yield nanoplate-filled subjected confining pressure. two kinds on properties nanocomposite comparatively examined. calculated results demonstrate that types imperfect interfaces between have significant influences behaviors composites.
