“…Details of the 45 ο chamfer used as a trigger in all models are shown in Figure 1(C). It was found from the drop test results [ 16 ] that the chamfer angle has no significant effect on the mean force of the laminated tubes so that no other chamfer angles were modeled. The geometric parameters of the tubes from Reference [16] used to validate the proposed modeling approach are given in Table 1.…”

The geometric parameters of the tubes from Reference [16] used to validate the proposed modeling approach are given in Table 1. It was observed during the tests that delamination and damage of the tube develop within a narrow zone in the loading direction, which is comparable with the tube thickness, while the stationary end was not affected by delamination or damage.…”

“…Besides, the force‐displacement curves possessed a notable uniformity. Due to this reason, models with a shorter length than the tested specimens with a typical length of 100 mm [ 16 ] were built in order to reduce the computational time for model validation. Models with tube lengths L = 65 mm for the full tube and L = 70 mm for the ¼ model are used.…”

“…Since the laminated tubes are likely to undergo significant bending deformation under impact loading (Ataabadi et al [ 16 ] ), the finite elements used to model these structures should be capable of capturing bending correctly (Bogenfeld et al [ 3 ] ). Thus, mid‐surface shell elements with six DOFs (three rotational and three transitional DOFs at each node) are promising candidates to model the intra‐ply behavior.…”

Finite element modeling ofCFRPcomposite tubes under low velocity axial impact

The dynamic axial crushing response of circular tubes made of unidirectional carbon fiber‐epoxy composite was investigated numerically applying a new approach to the modeling of the delamination process. In the proposed approach, delamination (interface damage) was modeled by inserting isotropic resin plies capable of damage. They are tied to the adjacent laminae and replace the commonly used surface‐based cohesive model. Two multi‐layer models of laminated tubes having cross‐ply and angle‐ply stacking sequences were simulated using stacked conventional shell elements layers to capture the crushing response and intralaminar and interlayer damage of laminated tubes. The progressive failure analysis in Abaqus/Explicit was utilized to model the successive damage of both the interface and laminae. Both the intralaminar layers and isotropic resin layers were modeled by the conventional reduced integration shell element (S4R). The suggested modeling technique offers some advantages compared to the main‐stream interface modeling of the axial impact of laminated tubes. The computational cost is reduced and yet accurate predictions are obtained. The FE models based on the proposed delamination approach were validated by experimental test results obtained by the authors for cross‐ply and angle‐ply tubes subjected to a low‐velocity impact.

“…A lot of recent work on the crashworthiness of common composite reinforcements including singular fiber systems of glass or carbon fiber-reinforced polymer structures has also been performed, including work by Ataabadi et al, 10 Chen et al, 11 Patel et al, 12 Kathiresan et al, 13 Jiang et al, 14 Striewe et al, 15 and Zhou et al 16 Among these studies, certain authors have also investigated structural geometries other than circular tubes including Kathiresan et al that have studied the low-velocity axial collapse behavior of E-glass fiber/epoxy composite conical frusta, and both Jiang et al and Striewe et al have investigated the crashworthiness of hat-shaped composite structures. Chen et al and Zhou et al focused on the axial crushing behavior of square tube profiles.…”

This article presents an experimental study on the quasi-static crushing performance of carbon fiber reinforced polymer (CFRP) rods consisting of unidirectional carbon fibers wrapped by braided glass fibers. Rods with and without a taper are tested and then inserted in extruded and expanded polystyrene foam and cardboard panels. Hybrid columnar aluminum tube–CFRP rod structures are also tested in all panel materials. These results are compared to those based on glass fiber reinforced polymer (GFRP) rods, GFRP rods in polystyrene foams, and to GFRP rods in cardboard from a previous study. Tapered CFRP rods exhibit progressive crushing behavior with specific energy absorption superior to GFRP rods, with values of 82 kJ/kg and 65 kJ/kg, respectively. Moreover, the highest specific energy absorption (111 kJ/kg) is obtained in hybrid columnar aluminum tube–CFRP tapered rods, exceeding values of aluminum tubes (89 kJ/kg) and equivalent structures containing GFRP rods (102 kJ/kg). Within panels, cardboard produces the largest increase in mean load of CFRP and GFRP rods due to most constraining fiber splaying during crushing, followed by extruded foam, and lastly expanded foam. However, crushing displacement is most restricted in cardboard due to earlier final compaction. The smallest variations in crushing load occur in extruded polystyrene due to greater homogeneity throughout the foam structure.

Reasonable design of induced holes on thin-walled structure is beneficial to enhance the crashworthy performance of the structure. In order to improve the crashworthiness of Al/carbon fiber-reinforced polymer (CFRP) tube, the effect of induced holes on the Al/CFRP thin-walled structure was studied, and the Al/CFRP tube configuration with better overall crashworthiness was obtained by multi-objective optimization design method. First, the quasi-static axial compression tests were carried out on the intact Al/CFRP tube and the Al/CFRP tube with induced holes, and a numerical model validated by the experiment was established. Second, the parameters of the induced hole were studied numerically to explore the influence of the induced holes on the crashworthiness of the Al/CFRP tube. It was found that the diameter and number of the induced hole had a great influence on the crashworthiness and energy absorption (EA) capacity. Finally, the multi-objective optimization was performed to optimize the parameters of the induced holes by integrating the Kriging model technique and the nondominated sorting genetic algorithm (NSGA-II). Compared the optimal design with the intact Al/CFRP tube, the first peak load is reduced by 24.32% and the specific EA is slightly improved by 0.68%.
