“…The general contact algorithm has the ability to enforce edge-to-edge contact for a wider range of edges, including geometric feature edges, perimeter edges of structural elements, and edges defined by beam and truss elements. Such interaction definition was widely used in the compressive simulation of cellular structure [27][28][29] and it was also suitable for the presented case.…”

Origami-based structures utilize the ancient art of origami to solve various engineering problems, particularly in energy absorption applications. This paper presented a newly designed truncated origami structure based on the Miura-ori pattern. As the truncated ratio 𝑒 decreased, the truncated structure gradually transformed from a Miura-ori structure to a condensed solid. The behavior of truncated origami structures under quasi-static compressive loading in the in-plane direction was analyzed through numerical simulations. The experimental results confirmed the validity of the simulation models. The truncated origami structure with varying 𝑒 was investigated, and the structure with 𝑒 = 0.6 exhibited the best overall energy absorption performance. The truncated origami structure was compared to honeycomb structures with the same relative density, and it performed better in specific energy absorption (𝑆𝐸𝐴) in two in-plane directions.

“…The original design objective of sandwich structures was to obtain high bending stiffnesses without increasing the weight using a low‐density core and high‐modulus skin. The common forms of sandwich structures include foams, 2 grids, 3 trusses, 4 and corrugations 5 . Notably, the compression, 6 bending, 7 vibration, 8 and impact resistance 9 performances have been investigated.…”

This article reports a carbon fiber–reinforced plastic Kagome composite honeycomb sandwich structure reinforced with polymethacrylimide (PMI) foam (PKCSS). Low‐velocity impact performances on the node, rib, and two cell centers of the PKCSS were experimentally compared with those on a composite Kagome honeycomb sandwich (CKHS), and the failure mechanism of the PKCSS was investigated. The impact process was analyzed through an explicit numerical analysis using ABAQUS. A three‐dimensional Hashin failure criterion was introduced using the VUMAT subroutine. Results confirmed that the PKCSS exhibits higher impact and specific loads than the CKHS, with the maximum improvements of 69.7% and 39.5%, respectively, under 50‐J impact energy. As an uncrushable material, the PMI foam provides strong impact resistance during its plateau stage. This technology of cell filling can be used to fabricate lightweight all‐composite honeycomb sandwiches for potential use in ultrahigh engineering applications.Highlights Cell filling is applied in an all‐composite Kagome honeycomb sandwich. The LVI performances of the PKCSS and CKHS are experimentally compared. C‐scanning is used to analyze the failure of the considered structures. The PKCSS's numerical model is established to investigate the impact process. The enhancement mechanism of the PMI foam is analyzed.

“…Sandwich structures are widely used in various industries due to their good bending properties, and their lighter mass [1].Meanwhile , different materials such as foam, Nomex, aluminum alloys, wood, laminated composites, and polymers have been used for the fabrication of sandwich structures [1][2][3][4] [5], and with the abundance of materials, 3D printing technology has started to be increasingly used for the fabrication and study of a wide variety of sandwich structures [6][7] [8][9] [10].Corrugated sandwich panels consist of a corrugated core and upper and lower panels, which have a higher resistance to bending load bearing capacity than the common foam, honeycomb, and lattice core sandwich panels [11].Corrugated cores possess different shapes, and the common triangular [12], trapezoidal [13], and rectangular cores [14] are widely used because of their simple structure, ease of fabrication, and mass production. In previous studies, the bending properties of corrugated sandwich structures have been extensively studied, and Xia et al investigated the mechanical response of aluminum corrugated sandwich panels with various core shapes, such as triangular and trapezoidal, under the action of longitudinal three-point bending, and parametrically studied the effects of corrugated core web thickness, length, and corrugation angle on the bending mechanical properties of corrugated sandwich panels, and optimized the design for trapezoidal core corrugated sandwich panels [15].Atar et al investigated and compared the bending stiffness and shear stiffness of corrugated sandwich panels including triangular, trapezoidal, and rectangular cores with a single core, and found that triangular and rectangular corrugated sandwich panels have the highest and lowest load carrying capacity, respectively, and the angle of the corrugated core web has a significant effect on the transverse shear stiffness of corrugated sandwich panels [16]. Rubino et al experimentally investigated the longitudinal bending of sandwich panels with Y-frames and corrugated cores and found that the corrugated sandwich panels with these two core shapes have similar bending mechanical responses under the same boundary conditions [14].…”

Single-layer core corrugated sandwich panels generally consist of a corrugated core and two layers of panels, while multi-layer core corrugated sandwich panels are formed by stacking multiple layers of panels with multiple layers of core layers. In this study, integrated multilayer core corrugated sandwich panels with different shapes of corrugated cores (triangular, trapezoidal, and rectangular) and the different number of core layers were fabricated using 3D printing technology, and the mechanical behavior of such multilayer core corrugated sandwich panels under quasi-static three-point bending was investigated using experiments and numerical simulations. The effects of core shape and number of core layers on the bending deformation process, damage mode, load carrying capacity, and bending energy dissipation capacity of multilayer core sandwich panels are discussed. Parametric design of multilayer triangular core corrugated sandwich panels was also carried out by finite element software ABAQUS. It was found that a new multilayer corrugated sandwich panel with a multi-layer core is better than the single core shape multilayer corrugated sandwich panel in terms of bending load capacity, energy dissipation capacity and deformation capacity can be obtained through the combination design of different core shapes.
