摘要
在 A- B模型的基础上 ,通过球腔膨胀模型和损伤力学 ,建立了一种新的侵彻贯穿有限厚靶板的工程分析模型 ,描述了侵彻贯穿的过程 .最后通过计算钨球对薄铝靶板的侵彻贯穿的算例和试验数据的比较 ,来说明这种方法不仅理论上有依据 。
In this paper, we developed a model that can describe the process of projectile with spherical nose penetrating limited-thickness targets. Penetration force can be calculated on the basis of the theory of dynamic spherical cavity-expansion approximation. On the theory of continual damage mechanics, the time when extrusion occurred can be taken and the length of extrusion also can be given too. Finally some penetration calculation results about a tungsten sphere to aluminum limited-thickness targets are presented to validate the reliability of the method.
