钨合金杆在线型聚能射流作用下变形断裂的机制及其特性

In order to study the deformation and fracture mechanisms and characteristics of tungsten alloy rod under the impact of linear shaped jet, the deformation and fracture characteristics of tungsten alloy rod under the impact of linear shaped jet are studied by static experiments. Based on the verification of the model, the interaction processes of the linear shaped jet on the static and the moving tungsten alloy rods at different angles are simulated by ANSYS/LS-DYNA, and their fracture characteristics and mechanism are analyzed. The results show that both the static and moving tungsten rods are broken into several sections under the impact of the linear shaped jet. The fracture of tungsten alloy rod is not due to the penetration of jet. The main mechanism of fracture is the tensile/shear failure caused by the deformation of tungsten alloy rod under the impact of the linear shaped jet. The position and section number of the fracture are related to the angle between them. The research results can provide data support for the design of a new type of reactive armor to intercept long rod projectiles.
