Abstract: Interphase around the reinforcement has significant influence on the interfacial stress, displacement and stiffness of composites. In this article two types of RVE models have been implemented using finite element analysis. Aluminum nitride nanoparticles were used as a reinforcing material in the matrix of AA2124 aluminum alloy. It has been observed that the nanoparticle did not overload during the transfer of load from the matrix to the nanoparticle via the interphase due to interphase between the nanoparticle and the matrix. The maximum tensile strengths of AlN/AA2124 nanocomposite have been found 535.40 MPa without interphase and 561.57 MPa with interphase. The transverse modulus has been established lower than the longitudinal modulus of AA2124/AlN nanocomposites. The results obtained from the finite element analysis were validated with mathematically derived and experimental results.
