“…In recent years, researchers have systematically studied the axial compression performance and energy absorption capabilities of tubular structures with different cross-sections, such as regular circular tubes, 5 square tubes, 6 as well as polygonal tubes, 7,8 through experiments and finite element numerical analysiss. For instance, Researchers such as Koloushani et al 9 and Wu et al 10 have investigated the deformation modes of circular thinwalled tubes. Circular thin-walled tubes can undergo deformation modes such as progressive folding, simple compression, inversion, cracking, and overall buckling, characterized by the formation of axisymmetric or diamond-shaped wrinkles.…”

Abstract3D woven tubular composites (3D‐WTC), known for their lightweight and high‐strength characteristics, are widely used in various energy‐absorbing components. To enhance the energy absorption capacity of 3D‐WTC, this study conducted a mechanical analysis of bamboo tube structures and proposed concentric circular nested biomimetic structures with “single tube + double ribs” and “double tubes + double ribs.” 3D woven tubular composites with bamboo‐structures (3DWTC‐Bamboo) were fabricated using the vacuum‐assisted resin transfer molding (VARTM) process. Axial compression tests were conducted using a universal testing machine to reveal and discuss the energy absorption capacity and failure modes of 3DWTC‐Bamboo. The results showed that 3DWTC‐Bamboo with a “double tube + double ribs” concentric circular nested biomimetic structures performed exceptionally, with a peak load of 28.93KN and specific energy absorption of 7.74 J·g−1. The failure mode was a hybrid of “rib folding + tube wall buckling.” Finally, finite element analysis of the stress distribution during the compression of 3DWTC‐Bamboo was conducted using ABAQUS, which validated the experimental results. In summary, this work provides a reference for structural innovation in 3D‐WTC and further expands its application in the field of energy absorption.Highlights Propose “single tube + double ribs” and “double tubes + double ribs” structures. Introducing the “rib” structures to enhance the local strength/stiffness. Test results show that 3DWTC‐Bamboo has great potential in energy absorption. The “ribs” can increase the local strength/stiffness of the tube structures.

“…Over the recent years, various energy absorber systems have been introduced and enhanced in pursuit of this goal. Expansion, [1][2][3][4][5] inversion, 6 crushing, 7,8 expanding-splitting [9][10][11][12] and shrinking-expanding of a deformable tube are different types but effective kind of energy-absorbing 13 approaches to improve the energy absorption characteristics of circular deformable tubes. The expansion angle and coefficient of friction between the deformable tube and mandrel are two main factors affecting energy absorption.…”

This paper investigates the expansion of circular aluminium tubes using a rigid die under quasi-static loading conditions through experiments and finite element simulations. This study primarily focuses on the expansion of thin-walled tubes with a thickness ranging from 3.95 to 5 mm, and the finite element model is in good agreement with the experimental results. Additionally, the study emphasizes the impact of the coefficient of friction, energy dissipation properties and the diameter-to-thickness ratio on the energy expenditure associated with the expansion process of aluminium tubes using a rigid die. This study use Digital Image Correlation (DIC) technology to evaluate pictures obtained during experimental procedures, enabling accurate quantification of displacements, stresses, and rotations of major planes. The findings indicate that the energy absorption resulting from friction plays a significant role, with the coefficient of friction serving as a important parameter throughout the expansion process. The energy absorbed by the friction between tube-die contact surfaces was significantly higher than that absorbed by the plastic bending of the aluminium tube. For specimen AT-5.0-1, the energy absorbed by friction and bending is 3352 and 570 J, respectively. Result shows that a notable increase in the ultimate load, rising from 46.03 to 61.54 kN, is required for expanding the aluminium tube with a thickness of 3.95 to 5.0 mm. The local strain patterns seen on the surface of the tube offer useful insights, therefore enhancing researchers’ ability to examine particular points on the specimen’s surface without the need for fixed reference points prior to conducting experiments.
