“…Lin and Lee [14] conducted experimental and numerical studies on the impact damage of laminated plates and cylindrical panels, finding that shell structures are more vulnerable to damage than plates when exposed to the same impact velocity conditions. The study by Palazotto et al [15] shed more light on the utilization of nonlinear shell theory to obtain the impact response of cylindrical panels, predicting deflections and stresses by experimental means. Kim et al's results contribute to our understanding of the dynamic behavior of curved laminated composite structures [16].…”

Curved glass enables designers to achieve unparalleled innovation in creating modern and undulating shapes for building enclosures. However, the curvature of panes changes the static and especially the dynamic behavior of the panes under loading. Studies on low-velocity impacts on curved glass have been limited and have primarily involved numerical studies. This paper experimentally investigates the dynamic response of cylindrically curved glass panes under a low-velocity impact. A flat, 5 mm thick, single-pane geometry with three curvature radii and the lack or presence of movement restraint is considered. Special attention is also paid to the variations caused by impacting bodies involving different stiffness, mass, and geometry parameters. It was found that flat plates have a lower capacity to dampen oscillations, resulting in longer decay times compared to curved panes. For impactors with a lower stiffness, the glass panes experience uneven oscillations at the moment of impact, followed by a chaotic period of transient vibrations before reaching a stationary state. This contrasts bodies with greater deformability in which the main dynamic behavior follows a more predictable pattern.

“…These papers show that the majority of published work has focused on impact of plates rather than curved structures. The detailed studies on the curved composite laminates have been seen after the 1990s [4–15]. Ambur and Starnes [9] showed that the plate radius and plate thickness were important structural parameters that influence the nonlinear response of a plate for a given impact energy.…”

This article presents experimental results of the impact response and failure characteristics of curved composite sandwich beam with debond. The objective of this study is to determine how the curvature and debond affects the contact force, displacement, absorbed energy, and damage type under impact loading. An instrumented drop-weight impact test are performed on sandwich beams made of carbon/epoxy face sheets and polyurethane foam core material with four different radii of curvature and debonds between the top and bottom interface of face sheet and foam core. Impact energy was kept constant of 4 J. The contact force and displacement histories of curved sandwich composites with debond are measured to determine the impact response. The results are compared with those of flat beams with the same dimensions and no debond. They indicate that the value of the contact force increases as the curvature angle increases for the beam with no debond. Opposed to the beams with no debond, the contact force decreases as the curvature angle increases for the beam with debond. These results show that curvature angle and debond are important mechanical parameters that must be considered in the design of structures.
