finite element method is employed in conjunction with a unit cell of the composite to investigate the compressive and tensile behavior of the system. An empirical elasto-plastic relation is used to describe the plastic flow behaviour of the matrix while grain size effects are included by the classic Hall–Petch relation. The boundary phase is assumed to have the mechanical properties of a quasi-amorphous material. The results of the calculations are compared with previously published experimental data. The agreement between results indicates the suitability of the model for nanocrystalline materials.
