摘要：

We developed penetration equations for ogival-nose projectiles that penetrated soil targets after normal impact. The spherical cavity-expansion approximation simplified the target analysis, so we obtained closed-form penetration equations. To verify our model, we conducted field tests into soil targets with 23.1 kg, 95.25 mm diameter projectiles and obtained rigid-body decelerations and final penetration depths. Model predictions show good agreement with measurements for five tests conducted at an impact velocity of 280 m s-1.
