Numerical simulations are conducted herein on the penetration of aluminum targets by ogival-nosed steel projectiles using the commercial FEM code ABUQUS. In the simulations, the response of the targets are represented by a forcing function, which is derived from spherical cavity expansion theory. This methodology eliminates the need for discretizing the targets as well as the need for a contact algorithm. It is shown that the numerical simulations are in good agreement with the available experimental data for the penetration of 6061-T6511 aluminum targets struck by VAR 4340 steel projectiles, reported in the literature. It is also shown that pitch and yaw or inclination angle has significant effects on the depth of penetration as well as projectile response.

基于球形空穴膨胀理论(SCE),采用ABAQUS有限元商业软件并结合其子程序的二次开发功能对钢弹侵彻金属靶进行3D有限元数值模拟。根据空穴膨胀理论,靶体对侵彻弹体的影响可以用一个作用在弹体表面的力函数代替,这样在进行数值模拟时就无须划分靶体网格,也避免了复杂的接触问题,从而使模拟大大简化。模拟所用卵形弹为VAR 4340钢弹,靶体为6061-T6511铝合金。模拟过程中考虑到弹体的可变形性和入射时的微小偏航角等实际情况,并且考虑到了弹身在运动过程中和靶体的接触分离效应。所得模拟结果与文献中的实验结果进行了比较,发现模拟结果与实验结果吻合得很好,并得到了一些有意义的推论。

基于球形空穴膨胀理论(SCE),采用ABAQUS有限元商业软件并结合其子程序的二次开发功能对钢弹侵彻金属靶进行3D有限元数值模拟。根据空穴膨胀理论,靶体对侵彻弹体的影响可以用一个作用在弹体表面的力函数代替,这样在进行数值模拟时就无须划分靶体网格,也避免了复杂的接触问题,从而使模拟大大简化。模拟所用卵形弹为VAR 4340钢弹,靶体为6061-T6511铝合金。模拟过程中考虑到弹体的可变形性和入射时的微小偏航角等实际情况,并且考虑到了弹身在运动过程中和靶体的接触分离效应。所得模拟结果与文献中的实验结果进行了比较,发现模拟结果与实验结果吻合得很好,并得到了一些有意义的推论。

Numerical simulations are conducted herein on the penetration of aluminum targets by ogival-nosed steel projectiles using the commercial FEM code ABUQUS. In the simulations, the response of the targets are represented by a forcing function, which is derived from spherical cavity expansion theory. This methodology eliminates the need for discretizing the targets as well as the need for a contact algorithm. It is shown that the numerical simulations are in good agreement with the available experimental data for the penetration of 6061-T6511 aluminum targets struck by VAR 4340 steel projectiles, reported in the literature. It is also shown that pitch and yaw or inclination angle has significant effects on the depth of penetration as well as projectile response.
