英文摘要：

Based on the structural signature of tungsten-fiber reinforced Zr-based bulk metallic glass matrix composites （BMGMCs） and homogenization theory, a theoretical model for calculating their equivalent elastic constants was established. The equivalent elastic constants of these composites were predicted by the proposed model combined with the finite element analysis. The effects of the volume fraction and size of the reinforced phases on the effective properties of tungsten-fiber reinforced BMGMCs were further studied. The results demonstrate that a combined approach of the homogenization theory and the finite element formulation can effectively predict the elastic properties of tungsten-fiber reinforced BMGMCs with periodic meso-structure and thus, providing bases for the rational design of this kind of composite.
