本文研究了重3.8g的钢制圆柱以700m/s的速度撞击铝板(厚5mm)的弹道冲塞问题,提供了冲塞破坏效应的实验数据,着重介绍了二维Lagrange 2DP程序对冲塞过程的数值模拟结果,研究表明,理论计算与实验结果吻合较好。
In this paper, we study the ballistic impact of a heavy steel 3.8g cylinder striking an aluminum plate (5mm thick) at a speed of 700m / s, and provide the experimental data on the failure effect of the piston. Emphasis is put on the two-dimensional Lagrange 2DP program Numerical simulation results show that the theoretical calculation is in good agreement with the experimental results.
