钨合金材料由于具有高密度、高强度特性,而且在冲击作用下的破坏模式表现为绝热剪切,所以常被应用于动能穿甲弹的设计。本文采用Abaqus/Explicit软件,对Couque开展钨合金流体动力学冒状剪切实验进行了数值模拟,给出了撞击速度与剪切带尺寸的关系,为更好地认识钨合金的动态破坏提供认识。 Tungsten alloy materials are often used in the design of kinetic energy armor-piercing bombs due to their high density and high strength properties and their failure modes under impact are adiabatic shear. In this paper, Abacus / Explicit software was used to simulate Couque fluid dynamics experiments on the sag shear, and the relationship between the impact velocity and the shear zone size was given to provide a better understanding of the dynamic failure of the tungsten alloy .
