摘 要:
利用MSC.Dytran中的具有强度的多材料欧拉网格模拟水滴和有限长连续射流对靶板（岩石）的高速冲击作用,研究了靶板破坏深度、破坏宽度与水滴初压力、速度、入射方向、板厚以及连续射流的密度等的关系及其物理意义.用应力波理论来解释靶板的层裂现象,试图多角度分析射流破岩机理.[著者文摘]

Abstract:
The dynamics of a single high-speed drip impacting with solid target are simulated by MSC.Dytran. The relations between the damage depth or damage width and the initial pressure, the velocity, the angle incidence of drips, the thickness of target are shown by curves, and the physical mechanism is explained. Hopkinson spallation is explained by using the theory of stress waves. The mechanism of water jet impacting rock is also discussed in this paper.[著者文摘]
Key words:
drip, damage depth, damage width
