“…Under LVI, complex damage patterns often present in composite laminated structures, which are hard to to detected. 17,30 In general, such damages can be classified into two categories : (i) fibers break, the matrix cracks, and other modes of intra-laminar failure occur within a ply; (ii) Inter-laminar failure mainly refers to the delamination between sub-layers. Since the inspired composite plate is extruded under the impact load, it is reported that some interlayer damage will not cause complete destruction of the material.…”

“…15,16 The helicoidal scheme is known to affect the face-on LVI response of fiber-reinforced laminates heavily by altering the damage mechanisms and the related propagation. 17 It slows down crack propagation to a certain extent by crack twisting, stopping, flexing or bridging. 18 Previous research on the structure of helicoidal laminates includes both non-linear and linear structures.…”

Through evolutionary processes, helicoidal structures have been proven to exhibit exceptional load‐carrying capacity and impact resistance performance. To date, extensive experimental and numerical studies have been carried out on their impact behaviors, while few relevant analytical studies have been reported even though it is urgently needed for the preliminary assessment of structure design and optimization. In this work, based on the first shear deformation theory (FSDT) and the improved linearized Hertzian contact method, an analytical model for low velocity impact (LVI) performances of helicoidal laminates with arbitrary layups is developed. Therein, the post‐impact damage is taken into account according to continuum damage mechanics (CDM). Comparisons of load‐carrying capacity and energy‐absorbed performance between the proposed model prediction and the existing experimental data\numerical results have been made for verification. Besides, LVI behaviors of conventional laminates with unidirectional distribution andcross‐ply arrangement are discussed. Moreover, the role of rotation angle, impact velocity and the plate dimension on helicoidal laminates' LVI performances are analyzed quantitatively. There is evidence that helical layouts are better able to absorb energy and delay the in‐plane damage.Highlights The LVI responses of bio‐inspired single‐helicoidal (SH) and double‐helicoidal (DH) composite laminate are studied. An effective model to predict the LVI responses considered the post‐impact damage is developed. A comparison of the LVI performance of single‐helicoidal structures with various lay‐up schemes is carried out. DH structure has better low velocity impact resistance than SH structure when the rotation angle shares the same.

“…10 Inspired by the helicoidal layup of the layers in the laminated composite structures, several researchers studied the influence of the impact of a foreign object over them. [11][12][13][14][15][16] The superiority of the helicoidal layup is present in those works. The selfrecoverability capacity of helicoidal laminates was demonstrated by Liu et al 17 Toughening mechanism in coelacanth fish-based helicoidal plates was studied by Yin et al 18 Figure 1 shows the different biological creatures from which the helicoidal structures can be obtained.…”

Helicoidal schemes possessed by biological creatures possess high strength and stiffness. The adoption of the layup configurations possessed by these biological creatures is not fully explored. The present article aims to carry out the free vibration analysis of biological-inspired laminated composite (B-ILC) plates having helicoidal layup. The analysis is carried out using higher-order zigzag theory (HOZT) as due to the presence of several layers, the HOZT can predict the behavior accurately compared to the shear deformation theory. Based on Hamilton’s principle, the governing equations are worked out and analyzed using the finite element method. The influence of boundary conditions, geometric properties, number of layers, the skew angle of the plate, and material properties on the free vibration behavior are studied in detail.

“…Bone is a highly optimized composite material with outstanding mechanical properties, which has a very complex structure and is organized at different levels (Wang et al, 2020;Ingrole et al, 2021). Composite materials with high strength, light weight (Rahimizadeh et al, 2021) and impact resistance (Wang et al, 2021;Wang et al, 2022) have a wide range of needs in the fields of aerospace, military, vehicles and other fields (Dong et al, 2022;Sharma et al, 2022). Therefore, the research of biomimetic composites can provide inspiration for the design of materials with excellent mechanical properties and meet the special requirements of engineering (Bhudolia and Joshi, 2018;Jiang et al, 2019;Alizadeh and Ebrahimzadeh, 2022).…”

Osteons are composed of concentric lamellar structure, the concentric lamellae are composed of periodic thin and thick sub-lamellae, and every 5 sub-lamellae is a cycle, the periodic helix angle of mineralized collagen fibers in two adjacent sub-lamellae is 30°. Four biomimetic models with different fiber helix angles were established and fabricated according to the micro-nano structure of osteon. The effects of the fiber periodic helical structure on impact characteristic and energy dissipation of multi-layer biomimetic composite were investigated. The calculation results indicated that the stress distribution, contact characteristics and fiber failur during impact, and energy dissipation of the composite are affected by the fiber helix angle. The stress concentration of composite materials under external impact can be effectively improved by adjusting the fiber helix angle when the material composition and material performance parameters are same. Compared with the sample30, the maximum stress of sample60 and sample90 increases by 38.1% and 69.8%, respectively. And the fiber failure analysis results shown that the model with a fiber helix angle of 30° has a better resist impact damage. The drop-weight test results shown that the impact damage area of the specimen with 30° helix angle is smallest among the four types of biomimetic specimens. The periodic helical structure of mineralized collagen fibers in osteon can effectively improve the impact resistance of cortical bone. The research results can provide useful guidance for the design and manufacture of high-performance, impact-resistant biomimetic composite materials.
