“…Hongyong Jiang et al [ 31 ] reported a theoretical of CFRP perforated square tube based on that of Hussein. [ 30 ] Liu et al [ 32 ] modified Hussein's [ 30 ] analytical model to study muti‐cell CFRP tube on the basis of the failure mode of the T‐shaped corner, which considered the interactive effect between the rib and tube wall in the T‐shaped part.…”

The CFRP-Al hybrid thin-walled structure combines the dual advantages of carbon fiber reinforced plastics (CFRP) and metal, which is one of the crucial methods for both lightweight and high strength. This study aimed to explore the theoretical prediction of the mean crushing force of the hybrid tubes with different winding angles subjected to axial compression. In order to construct the theoretical model of the hybrid structural energy absorption response, the failure modes, and deformative behavior of the hybrid tubes are analyzed and summarized based on the axial compression experiments. Considering the effects of winding angles on the energy dissipation and deformation characteristic of hybrid circular tubes, the expressions of membrane force and binding energy per unit length are obtained. Then, the analytical model is established to predict the mean crushing force of the CFRP-Al hybrid circular tube. Furthermore, the results of the prediction model are compared according to different failure criteria of composite materials. The findings show that the predicted values of the maximum stress failure are more consistent with the experimental values, in which the discrepancy between analytically predicted and experimentally tested mean crushing forces of these hybrid tubes is no more than 10%. The results can provide a basis for the design of the composite-metal hybrid thin-walled tube.

“…As it is available in LS-Dyna software, the MAT54 enhanced composite damage model is often used in the simulation of crushing of tubes [22][23][24][25][26][27]. It produces quite good results, with an overall good representation of petals inside and outside the tubes, but as written in [23], there are too many non-physical parameters to identify and calibrate that the field of application is quite limited, and such a model cannot be described as predictive.…”

“…[4][5][6] When two or more types of continuous fiber are mingled to reinforce polymer matrix bar, the resulting product is called hybrid fiber reinforced polymer (HFRP) bar, [4][5] which is a solution to convert the brittle fracture of conventional FRP bar into plastic failure. [7][8][9][10] Over the last decades, the conventional FRP bars reinforced structural concrete has been extensively put into engineering application under the harsh environment, [11][12] involving in roads, bridges, parking lots, ports and offshore drilling platforms, [13][14][15] which improves the durability and mechanical properties of column, beam, slab, and shear wall structures. [16][17][18] The overall properties of FRP bar are usually dependent on the type of fiber and resin, the volume fraction of fiber, and the bond strength of fiber-resin transition interface.…”

In this study, a new test method, namely, the direct shear method was proposed to obtain the interlaminar shear strength (ILSS) of hybrid fiber reinforced polymer (HFRP) bars, which combined the advantages of standard methods in ASTM-D4475 and ASTM-D3914. The test device matched with this new method was also developed. Meanwhile, to verify the validity of this method, a total of 165 specimens were prepared to test the ILSS of carbon/glass-HFRP bars based on the proposed and other two existing standard methods, respectively. Additionally, the effects of the volume fraction and distribution pattern of carbon fiber, and the volume fraction of resin on the ILSS of carbon/glass-HFRP bars were systematically studied. The results show that the ILSS of carbon/glass-HFRP bars slowly decreases with the increase in the volume fraction of carbon fiber, and the ILSS of carbon/glass-HFRP bars with the dispersed distribution of carbon fiber is averagely 14.7% higher than that of specimens with the centralized arrangement of carbon fiber. The ILSS of carbon/glass-HFRP bars first rises and then reduces with the increase in the volume fraction of resin until it is nearly 40%.
