title = "Fem analysis on the {"}self-sharpening{"} behavior of tungsten-fiber/metallic glass matrix composite long rod",
abstract = "The geometrical model of tungsten-fiber / metallic glass matrix (WF/MG) composite long rod is established based on the microstructure of composite, and a modified coupled thermomechanical constitutive model is employed to describe the high shear sensitivity of metallic glass (MG) matrix. Then FEM simulations on the penetration of WF/MG composite long rod into steel target are conducted integrated with related penetration tests. Corresponding analysis shows that due to the high shear sensitivity of MG matrix, a significant {"}selfsharpening{"} behavior occurs in the composite rod, and the rod nose maintains as a sharp shape during the penetration. Comparatively, for the tungsten heavy alloy (WHA) rod, the nose blunts as a {"}mushroom{"} shape due to the relatively high plasticity of material. Correspondingly, the {"}self-sharpening{"} property of composite rod leads a much better penetrating performance compared with the WHA one.",
