Abnormal Tribological Behavior of Multiwalled Nanotube Rafts Part II: Inclined Rafts

Abstract

The analysis in part I of this series is extended to the case of inclined and randomly distributed multiwall carbon nanotube (MWCNT) rafts that are brought into contact. The MWCNTs are modeled by elastic and cylindrically anisotropic materials. The JKR theory of adhesion is adopted. With the incorporation of three-dimensional contact configuration that features the inclined contact, we are able to show that the abnormal tribological behavior, in drastic contrast to the classical Amonton’s law, persists for both inclined and randomly oriented rafts.
