The formation mechanism of adiabatic shear band under the impact load of tungsten alloy has been studied, and the influence of stress conditions has been investigated emphatically. The stepped cylindrical, dumbbell-shaped and straight cylindrical tungsten alloy specimens were subjected to impact loading using a split Hopkinson pressure bar apparatus. The microstructures of the impacted specimens were observed with an optical microscope. ABAQUS large-scale numerical analysis software was used to test For the finite element analysis, the material model uses the Johnson-Cook model in the form of thermo-viscoplasticity. The experimental and numerical results show that the stress conditions have an important effect on the deformation, damage (micro-cracks and adiabatic shear bands) and the failure modes of tungsten alloy.
