In this paper, with introducing a new simplified 3-D Representative Volume Element (RVE) for a wavy carbon nanotube (CNT), an analytical model has been developed to study the stress transfer in single-walled carbon nanotube (SWNT) reinforced polymer composites (NRPCs). The model is capable of predicting axial as well as interfacial shear stresses, along a wavy CNT embedded in a matrix. Based on the pullout modeling technique, the effects of waviness, wavelength and matrix modulus on axial and interfacial shear stresses have also been analyzed in details also using the statistical multiple non-linear regression method, the best-fitted functions for the interfacial stresses of CNT/polymer composites are obtained. The results of the present analytical model are in good agreements when compared with the corresponding results for straight NTs.
