“…Different from traditional structures, origami structures possess a few remarkable and novel characteristics, including reconfigurable configuration, tunable stiffness [70], negative Poisson's ratio, high folding ratio [71], multistability [69], satisfactory strength [72], and energy absorption capacity [73].…”

“…You et al [79] introduced origami patterns into the design of thin-walled square tubes to improve the energy absorption of components under axial compression. To promote the popularization and application of origami structures in automotive energy absorption boxes, Ma et al [73] and You et al [61] put forward a series of origami thin-walled tubes, and they carried out numerical simulations and dynamic impact tests on these structures. The results show that the energy absorption characteristics of these origami structures are better than those of traditional square tubes.…”

In recent years, origami structures have been gradually applied in aerospace, flexible electronics, biomedicine, robotics, and other fields. Origami can be folded from two-dimensional configurations into certain three-dimensional structures without cutting and stretching. This study first introduces basic concepts and applications of origami, and outlines the common crease patterns, whereas the design of crease patterns is focused. Through kinematic analysis and verification on origami structures, origami can be adapted for practical engineering. The novel characteristics of origami structures promote the development of self-folding robots, biomedical devices, and energy absorption members. We briefly describe the development of origami kinematics and the applications of origami characteristics in various fields. Finally, based on the current research progress of crease pattern design, kinematic analysis, and origami characteristics, research directions of origami-inspired structures are discussed.

This investigation focuses on the multiobjective optimization of a crash box subjected to static loading by using a validated numerical model and an analytical approach. The crash box is made with a unique combination of three materials: an aluminium tube filled with polyethylene terephthalate (PET) foam and a glass-fibre reinforced polymer (GFRP) skeleton. A finite element model was calibrated based on the results obtained in a material testing campaign using appropriate constitutive equations. A J2-plasticity model was used for the material behaviour of the aluminium alloy, and the PET foam was modelled using Deshpande and Fleck's model. Regarding the short-fibres GFRP, a Voce plasticity model was fitted to the experimental data. After a successful validation of the finite element model, the filled aluminium tube was subjected to a structural optimization to achieve the best crash performance. Three relevant design variables were selected: the thickness of the outer aluminium cylinder, the thickness of the GFRP and the density of the PET foam, the last being related to the crushing strength of the foam. Given the high computational cost of each finite element model, a multi-adaptive regression splines metamodel was fitted to a large-scale sampling. Optimum pairs were obtained for the absorbed energy, the specific energy absorption, the peak load and the mass of the com- the component over the design region selected for the optimization, and was also used for its optimization with satisfactory results.

“…Many efforts have been thus taken to reduce the initial peak force while keeping or increasing the absorbed energy, ranging from introducing dents and grooves (Mamalis et al, 1986;Yang et al, 2017), corrugations (Singace and El-Sobky, 1997;Wu et al, 2016) into square and circular tubes. Lately, researchers have found that the introduction of origami patterns into thin-wall structures can trigger specific failure modes, which in turn change the structural responses and characteristics.…”

Thin-walled tubes are widely used as energy absorption devices for their low cost and high manufacturability. Introduction of the origami technique enables the tube to follow a pre-determined failure mode and to improve its energy absorption efficiency. This paper examines the energy absorption characteristics of the origami crash box under quasi-static axial crushing. Both experimental and numerical results show that the origami pattern develops a diamond-shaped mode, bringing a reduction in initial peak force and a significant increase in energy absorption compared to the conventional hexagonal tube. The sensitivity of its energy absorption performance to various parameters is studied, and it is shown to achieve 68.29 % increase in the specific energy absorption and 13.91 % reduction in the initial peak force in the optimal case. Furthermore, an analytical solution is presented for the energy absorption, which achieves reasonable agreement with the numerical results.Published by Copernicus Publications.
