摘要
采用累积损伤模型,应用MMIC3D程序,研究了动能弹垂直和斜侵彻混凝土靶体的过程,探讨了不同头形的动能弹对侵彻效果的影响,其三维图像显示了动能弹对混凝土靶体的损伤效应以及混凝土靶体中应力波的形成和传播.
In this paper, using the code MMIC3D, the process of the ball projectiles penetrating uprightly and slantingly concrete target is discussed. And we have considered the penetration effect of these projectiles with different shape of nose. Their 3D images illustrates the damage effect of the concrete and the stress wave propagation in the concrete target.
