Necessity of Strain Hardening to Augment Load Bearing Capacity of AA1050/AlN Nanocomposites

In this article two types of RVE models have been implemented using finite element analysis. Aluminum nitride (AlN) nanoparticles were used as a reinforcing material in the matrix of AA1050 aluminum alloy. It has been observed that the nanoparticle did not overload during the transfer of load from the matrix to the nanoparticle due to interphase between the nanoparticle and the matrix. The tensile strength has been found increasing with change of strain hardening process from H-14 to H-18. The stress concentrations were found to be low in the nanocomposites having interphase between the matrix and the nanoparticle. The load bearing ability has been found increased as the interphase became stiffer with change of strain hardening process form H-14 to H-18.
