“…Many researchers are utilized this process for fabrication of energy absorbing structures. Shen et al [69] compared the EA performance of origami-inspired infill structures with circular and hexagonal tubular structures under quasi-static lateral loading and the origami-inspired infill tubular High accuracy and good surface finish structures are fabricated using material extrusion type fused filament fabrication technique. Kladovasilakis et al [70] investigated the EA behaviour of ABS lattice sandwich structures which were fabricated using material jetting printing and fused filament fabrication technique.…”

Thin-walled energy absorbing structures based on hybrid structural concepts have a lightweight benefit along with great potential of enhancing the crashworthiness characteristics. Inspired by the huge number of research investigations performed on novel additively manufactured hybrid metal-composite configurations and their latest developments, the current review article extensively reports the latest advances along with promising outcomes of the impact response of various additively manufactured hybrid metal-composite structures for crashworthiness applications. Specific consideration is given to the crushing performance of the hybrid structures fabricated from Fused deposition modelling technique. The significant additive manufacturing techniques, their material selections and exceptional customized structural designs explored in recent times are discussed elaborately. Crushing patterns obtained by hybrid energy absorbing structures under various loading conditions are recognized. Furthermore, comparison of various hybrid structures and their latest advances revealed the efficiency of the thin-walled hybrid configuration based on 3D printing techniques in terms of weight reduction, crashworthiness and energy absorption behaviour. This review article will serve as a catalyst to boost the scientific improvement of hybrid energy absorbing structures utilized as passive safety protective devices in modern vehicles.

The design of effective and compact energy absorption systems is key to the survivability and durability of many man-made structures and machines. To this end, this work presents the design, assessment, and implementation of a novel origami-inspired energy absorber that is based on the Kresling origami pattern. The absorber consists of a Kresling origami column positioned between the loading point and an energy dissipation module. By exploiting its unique inherent translation-to-rotation coupling feature, the primary function of the Kresling column is to transmit uniaxial incident loads (shock or impact) into localized rotational energy that can then be dissipated in a viscous fluid chamber. The proposed system has several unique advantages over traditional designs including the ability to i) dissipate energy associated with both torsional and uniaxial loads, ii) control the rotational velocity profile to maximize energy dissipation, and iii) customize the restoring-force behavior of the Kresling column to different applications. Furthermore, the proposed design is more compact since it can realize the same stroke distance of the traditional translational design while being considerably shorter. Through extensive computational modeling, parametric studies, and experimental testing, it is demonstrated that the proposed design can be optimized to absorb all the imparted energy; and out of the absorbed energy, around 40% can be dissipated in the viscous fluid, while the rest is either dissipated by the viscoelasticity of the origami column or stored in it as potential energy.
