Search of an equation of state for nanomaterials

Abstract

An effort is made to search a suitable equation of state (EOS) model for the nanomaterials. Six EOS models based on different physical origins viz. Brich-Murnaghan model, Murnaghan model, Kumar model, Vinet model, Freund and Ignalls model and Tallon model are used to study the compression behaviour of thirty one nanomaterials. The results are compared with the available experimental data. It is concluded that the Murnaghan model performs well for the materials considered in the present paper for the pressure ranges considered in the experimental studies of these materials. It is also discussed that the Murnaghan model may be obtained using different concepts.
