A dynamic cylindrical cavity expansion penetration model for compressible, elastic-plastic, rate-independent materials with power-law strain-hardening was presented. A fortran code using this model was written. We used the code to calculate the stress distribution in the target. We also used the code to predict residal velocities and ballistic limits for rigid, conical-nose projectile perforating strain-hardening target plates, and to predict the penetration depth for the same projectile penetrating into strain-hardening targets with semi-infinite thickness. We compared the model predictions of residal velocities and ballistic limits with the data from experiments with 0.026 kg tungsten projectiles impacting normally 5083-H131 aluminum armor plates. We also compared the predicted penetration depths with the experimental data or the 2-D numerically simulated results by LTZ-2D code for the 0.024 kg and the 2.96 kg maraging steel projectiles impacting normally semi-infinite 6061-T651 aluminum armor targets. Good agreements were obtained in both comparisons.

给出了适用于可压缩、弹塑性、按幂次律应变硬化材料的动态柱形腔膨胀模型和侵彻模型,并编制了相应的计算程序。腔膨胀模型给出靶中应力分布情况,侵彻模型根据腔膨胀模型的有关结果来预估具有锥形头部的刚性弹丸侵彻半无限厚靶的最终侵彻深度以及贯穿薄靶时的弹丸剩余速度和弹道极限速度。给出了钨合金弹丸正碰5083-H131铝靶和钢弹丸正碰6061-T651铝靶的一些计算结果,计算结果与实验结果及二维拉氏弹塑性LTZ-2D程序的数值模拟结果符合得很好。

给出了适用于可压缩、弹塑性、按幂次律应变硬化材料的动态柱形腔膨胀模型和侵彻模型,并编制了相应的计算程序。腔膨胀模型给出靶中应力分布情况,侵彻模型根据腔膨胀模型的有关结果来预估具有锥形头部的刚性弹丸侵彻半无限厚靶的最终侵彻深度以及贯穿薄靶时的弹丸剩余速度和弹道极限速度。给出了钨合金弹丸正碰5083-H131铝靶和钢弹丸正碰6061-T651铝靶的一些计算结果,计算结果与实验结果及二维拉氏弹塑性LTZ-2D程序的数值模拟结果符合得很好。

A dynamic cylindrical cavity expansion penetration model for compressible, elastic-plastic, rate-independent materials with power-law strain-hardening was presented. A fortran code using this model was written. We used the code to calculate the stress distribution in the target. We also used the code to predict residal velocities and ballistic limits for rigid, conical-nose projectile perforating strain-hardening target plates, and to predict the penetration depth for the same projectile penetrating into strain-hardening targets with semi-infinite thickness. We compared the model predictions of residal velocities and ballistic limits with the data from experiments with 0.026 kg tungsten projectiles impacting normally 5083-H131 aluminum armor plates. We also compared the predicted penetration depths with the experimental data or the 2-D numerically simulated results by LTZ-2D code for the 0.024 kg and the 2.96 kg maraging steel projectiles impacting normally semi-infinite 6061-T651 aluminum armor targets. Good agreements were obtained in both comparisons.
