This method has been successfully employed to similar problems by many researchers (Jam et al. 2013; Sobhani Aragh et al. 2012). Mori–Tanaka model can be developed by utilizing the elastic properties of the nanocomposite containing transversely isotropic aligned CNT or the orthotropic wavy CNT and the isotropic elastic properties of the pure epoxy. In case of two-phase composite, where the inhomogeneity is randomly orientated in the three-dimensional space, the following relation can be used to determine the effective stiffness tensor [C] of the nanocomposite: ½C ¼ ½Cm þ vRVE ÀÂ Ã Á CRVE À ½Cm ½A½vm ½I þ vRVE h½AiÀ1 ð1:35Þ in which the mechanical strain concentration tensor [A] is given by h Â Ã Ã ÀÂ ÁiÀ1 ½A ¼ ½I þ SRVE ð½Cm ÞÀ1 CRVE À ½Cm ð1:36Þ where [Cm] and [CRVE] are the stiffness tensors of the epoxy matrix and the RVE, respectively; [I] is an identity matrix; vm and vRVE represent the volume fractions of the epoxy matrix and the RVE, respectively; and [SRVE] indicate the Eshelby tensor (Mori and Tanaka 1973).
