“…Compared with low-velocity impact, the mechanical behaviors of structures under highvelocity impact, explosion and other strong dynamic loads are more complex. When the multistable mechanical metamaterials with macroscopical element size are subjected to these dynamic loads, their steady-state transition time is significantly longer than the response time of base materials due to the combination of the ultra-high strain rate effect of the material and the inertia effect of the structure [165][166][167]. In other words, the base material has undergone plastic deformation or failure before the occurrence of multistability [23].…”

Multistable mechanical metamaterials are a type of mechanical metamaterials with special features, such as reusability, energy storage and absorption capabilities, rapid deformation, and amplified output forces. These metamaterials are usually realized by series and/or parallel of bistable units. They can exhibit multiple stable configurations under external loads and can be switched reversely among each other, thereby realizing the reusability of mechanical metamaterials and offering broad engineering applications. This paper reviews the latest research progress in the design strategy, manufacture and application of multistable mechanical metamaterials. We divide bistable structures into three categories based on their basic element types and provide the criterion of their bistability. Various manufacturing techniques to fabricate these multistable mechanical metamaterials are introduced, including mold casting, cutting, folding and three-dimensional/4D printing. Furthermore, the prospects of multistable mechanical metamaterials for applications in soft driving, mechanical computing, energy absorption and wave controlling are discussed. Finally, this paper highlights possible challenges and opportunities for future investigations. The review aims to provide insights into the research and development of multistable mechanical metamaterials.

“…Currently, honeycomb sandwich structures are widely used in aerospace, aviation, and marine sciences as materials with excellent compressive and impact performance. 3 Specifically, these materials are implemented as energy absorbers, load-carriers, and sound insulators, serving as multi-functional protective components in devices. However, honeycomb sandwich structures are limited by closed cells, which make the structures prone to condense vapors, gain weight and lose the bonding capability between the panels and the core.…”

Foldcore sandwich structure has promising applications for load-bearing, and in this study, M-type foldcore sandwiches are prepared through a molding and pressing process with fiberglass. To be specific, the sandwich structures are investigated for dynamic response and damage mechanism under low-velocity impacts with various impact positions and energy. The results show that impact position significantly affects the damage mode of the sandwich plate, the damage mode of crush fracture and collapse failure at node position can dissipate higher energy compared with tensile fracture at base position. Moreover, the impact energy shows a certain influence only when the sandwich panel is not penetrated. Besides, numerical prediction closely matches experimental results in terms of load-displacement and energy-displacement histories. Effects of geometric configuration are explored, and the results suggest that although increasing the thickness of panel and core can effectively improve the load-bearing capacity under low energy impacts, increasing the core thickness is a more effective method in lightweight design than increasing the thickness of plane. Furthermore, the impact resistance can be enhanced by selecting the appropriate platform length and narrowing the platform angle. Notably, M-type foldcore sandwich is superior to V-type foldcore sandwich and corrugated sandwich in terms of specific energy absorption.

“…The whole saw blade after additive manufacturing is strengthened by quenching, then its superstructure strength is di cult to guarantee. The typical honeycomb hexagonal plate structure with excellent vibration reduction effect has been well known [29]. Resin material as a typical energy-absorbing material has been proved by many scholars [30,31] and has been widely applied.…”

Cemented carbide circular saw blades are widely used in the metal and nonmetal manufacturing industry for cut-off and cut-tail production. High energy consumption and intense noise emission from conventional-type blades are urgent environmental issues to be solved. Hence, a laminated-resin blade is proposed to study the effect of adding a damping structure to the blade body on its cutting performance.Apart from reduced energy consumption, lower noise and high-quality surfaces are required by manufacturers. In this work, a laminated-resin blade and a conventional blade were compared regarding the details of cutting force and energy consumption, noise emission, and surface integrity. In addition, the effect of cutting uid on conventional saw blades was analyzed in terms of cutting force and noise emission. Experimental results show that the cutting force and noise of the laminated-resin blade were less than that of the conventional one, indicating reductions of 27.8% and 18 dB, respectively. Especially a reduction of more than 20 dB sound level was achieved in the high-frequency band. Lower cutting force attained by the laminated-resin blade showed that smoother cuts could be achieved. Cutting with cutting uid is superior to dry cutting in terms of cutting force, noise level, and workpiece surface integrity. The research sheds new light on the design of damping structures on saw blade bodies and quantitative analysis of the cutting performance.
