| 摘 要： | 在已建立的应力波传播模型和研究弹、板间作用力所获结果的基础上，为分析复合板应力的变化，对复合板弹板碰撞承受的应力进行了简化处理，根据应力波传播特性，确定了复合板内能量集中区域，研究了应力波在复合板巾的传播和能耗，并讨论了应力波对陶瓷的作用。通过近似计算，发现烧蚀消耗的弹丸动能较大，在复合板中，Al板的塑性变形吸收了19％的弹丸动能。 |

| Abstract: | Based on the model of stress wave propagation in boron carbide/aluminum composite and the study of the stress between projectile and plates, the stress in the composite is simplified. According to the property of stress wave propagation, the energy concentrating area the composite is determined. Then the stress wave propagation and the energy consuming are investigated, and the process of stress waves acting on the ceramic is studied. Finally, it is found that the kinetic energy consumed by the bullet ablation is great and the initial kinetic energy consumed by the plastic deformation of aluminum plate is to up to 19%. |
