“…As happened with the force measured by the load cell, all contact force histories present the same trend and the peak force increases as the ice diameter and velocity raise. The duration of the pulse for a given impact velocity, rises as the ice diameter increases as expected (this observation could be identify for high velocity impacts cases); this effect was also observed in the work of Kim and Kedward [18]. Regarding the variation of the impact velocity for a given ice diameter, the duration of the pulse diminishes slightly as the impact velocity increases; this behaviour is expected since the duration of the impact should be proportional to the impact velocity.…”

“…Some of them focused on the impact on plates of different materials (mainly composite laminates); Kim et al [4,[17][18][19] published several works in which the high velocity impact of ice on composite laminates was investigated. In one of these works [19] the force induced by the ice during the impact in a reduced range of impact energies is analysed.…”

“…It was found that the damage modes depend on the impact energy and the failure threshold energy is proportional to the thickness of the specimen normalized by ice sphere diameter. Kim and Kedward [14] also conducted numerical simulation of ice impacts. The model was improved by Keune [16] by using adjustable ice properties to account for strain rate dependency.…”

Nowadays, more and more aircraft components are made of composite sandwich structures, and ice impacts are prone to cause internal damage to composite sandwich structures, so it is crucial to study the impact of hail on composite sandwich structures. Since hail impacts may occur several times at a single point, an experimental approach was used to investigate the dynamic response of GFRP/Nomex honeycomb sandwich panels under multiple hail impacts. The dynamic response of the structure was investigated in terms of response rate and deflection‐profile curves using 3D digital image correlation methods, and the effects of impact energy, hail size, and number of impacts on the impact resistance of the honeycomb sandwich structure were explored. The results show that the dynamic response process of sandwich panels can be categorized into the ball‐and‐crown phase, the rebound phase, and the vibration phase. Under the same impact energy, the impact of small‐sized hailstones is more threatening to honeycomb sandwich panels. As the number of impacts increases, the maximum deflection value of the back panel first increases uniformly, and when the layered damage area reaches the threshold value, fiber stripping occurs, and the increment of the maximum deflection value increases significantly.Highlights Since hail impacts may occur several times in real situations, this study conducted multiple impact experiments for one impact site. The dynamic response and damage pattern of the GFRP/Nomex honeycomb sandwich panels under multiple hail impacts were also investigated. The dynamic response process of GFRP/Nomex honeycomb sandwich panels was categorized into three phases: ball‐crown stage, rebound stage, and vibration stage. With the increase of the number of impacts, fiber stripping and fiber break damage began to occur when the layered damage area of the panel reached the threshold value. The honeycomb core has three main failure modes: cell wall folds, cell wall fracture, and cell wall debonding at the TGPW interface. Small‐diameter hails pose a more significant threat of damage to honeycomb sandwich panels at the same impact energy.
