摘要

The dynamic behavior of ice perforation has a great application background. This study investigates the perforation mechanics of an ice plate through experimental and numerical methods. Dimensional analysis is performed to identify the governing factors for the residual velocity of the projectile, the maximum deceleration of the projectile, and the damage diameters of the ice plate. Results show that: (1) The residual velocity of the projectile increases with its mass and impact velocity but decreases with ice plate thickness. The maximum deceleration of the projectile rises with impact velocity and ice plate thickness while declining with its mass. (2) The damage diameter on the impact surface of the ice plate grows with impact velocity, whereas the back-surface diameter remains velocity-insensitive. The damage diameters on both ice surfaces expand with ice plate thickness but show no clear dependence on projectile mass. Based on the simulation results, the scaling laws and predictive formulas for these concerned parameters are proposed. These results provide quantitative insights into ice perforation dynamics, advancing predictive capabilities for engineering design.
