Abstract

Abstract

Integrated with the relevant penetrating tests, the ballistic behavior of the tungsten fiber/metallic glass matrix (WF/MG) composite segmented rod is systematically investigated based on the meso-scale finite element method (FEM), and the comparative analysis on the penetrating performance is conducted between the composite segmented rod and the composite long rod. Related analysis shows that the composite long rod has the remarkable “self-sharpening” behavior as well as good penetrating performance, the “self-sharpening” in the composite segmented rod is less significant, and particularly, dispersal of the reinforced fibers is easily to occur in the structure. Correspondingly, the penetrating capability in the composite segmented rod is remarkably weakened compared with that in the long rod. In addition, the segmental number and the segmental interval have considerable effects on the ballistic behavior; however, the penetrating performance of the composite segmented rods with various structures is always lower than that of the composite long rod.
