摘要：

In order to predict the real-time penetration depth of all ogive-nose projectiles into concrete targets, a new method was developed based on the acceleration data measured in penetration tests with ogive-nose projectiles into semi-infinite concrete targets. With the proposed method, the whole penetration process was divided into three stages with instantaneous velocity, and each stage was described with different models. Through judging the calculation error, threshold velocities between stages were automatically determined. At the same time, the initial striking velocity of a penetration process was calculated by using the measured acceleration curve on the whole trajectory. It was shown that the predicted values with the proposed method are in reasonably good agreement with the measured data from tests. © 2017, Editorial Office of Journal of Vibration and Shock.
