Energy absorption of Kresling pattern thin-walled structures with pre-folded patterns and graded stiffness
Traditional thin-walled structures are widely employed in several energy-absorbing engineering fields, and origami patterns inspire novel structures with unique functionalities in this area. In this study, we explore energy-absorbing effects of origami-inspired thin-walled structures from perspective of the predicted stability of the Kresling origami. Our research utilizes finite element analysis and experimental validation to evaluate and contrast the energy-absorbing effects of the Kresling origami-inspired thin-walled structures (KOI-TWSs) with a traditional hexagonal thin-walled structure (HTWS). The results indicate that introducing the Kresling origami pattern into the thin-walled structure to obtain geometric defects (pre-folded pattern) and graded stiffness, and their effects are reflected in improving the buckling deformation stability or reducing the initial peak force. These effects depend on the predicted stability of the Kresling origami and are intuitively reflected in the geometric parameters. On the other hand, the reusability of materials is worth considering for improving the energy absorption of the thin-walled structures. These works provide new contents and perspectives for the KOI-TWSs.
期刊介绍:
The International Journal of Solids and Structures has as its objective the publication and dissemination of original research in Mechanics of Solids and Structures as a field of Applied Science and Engineering. It fosters thus the exchange of ideas among workers in different parts of the world and also among workers who emphasize different aspects of the foundations and applications of the field.
Standing as it does at the cross-roads of Materials Science, Life Sciences, Mathematics, Physics and Engineering Design, the Mechanics of Solids and Structures is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from the more classical problems of structural analysis to mechanics of solids continually interacting with other media and including fracture, flow, wave propagation, heat transfer, thermal effects in solids, optimum design methods, model analysis, structural topology and numerical techniques. Interest extends to both inorganic and organic solids and structures.
