“…Inc., Japan), which can evaluate velocities from 50 to 2000 m/s and also sense an object more than 5 mm in diameter. This system uses a planar sensor (500 mm × 300 mm) with a long-wavelength IR beam, which is capable of detecting an incident bullet in more detail [28,29]. To confirm whether the incidence bullet was perpendicular to the surface of the bulletproof material, an incidence angle detector was placed in front of the material at a distance of 1.0 m. 15 cm behind the bulletproof material, we placed a 0.5-mm-thick Al witness plate to verify whether the bulletproof material was penetrated [ Fig.…”

“…In these engineering applications, dynamic loadings are often encountered. Under dynamic loading, the response of honeycombs is significantly different from that under static loading [1][2][3][4][5][6][7][8][9][10][11][12][13], and honeycomb structures designed with static properties are usually too conservative and wasteful. Much effort has been made on the in-plane dynamic compressive properties of honeycombs [14][15][16][17][18][19].…”

“…Previous works have looked into crosssectional shapes [1,4], composite materials [5][6][7], and multi-step energy absorbing devices [8,9]. Thin-walled structures filled with aluminum honeycombs [10][11][12][13][14][15][16] and polymeric or metallic foams [17][18][19][20] as well as multi-cell tubes [21][22][23][24][25] have been suggested for better crashworthiness properties of energy absorbers. Composite materials have also demonstrated the mechanical advantages of crashworthiness over classical metals [26], i.e., crushing energy absorption per unit of mass [27][28][29].…”

To maximize the controllable energy absorption of corrugation troughs as observed in the single sided corrugated (SSC) tube, we proposed and tested a new structure design, i.e., double-sided corrugated (DSC) tube made of Al 6060-T6 aluminum alloy or CF1263 carbon/epoxy composite. Finite element models were developed to test the mechanical advantage of the DSC tube in comparison with both SSC and classical straight (S) tubes under axial crushing. Results have shown that the total absorbed energy of the DSC aluminum tube with 14 corrugations was 330% and 32% higher than that of the SSC tube with 14 corrugations and the S-tube, respectively. The initiation and progression of the crushing process for different tube configurations were characterized, leading to the mechanism of energy absorption. Plastic deformation in terms of PPEQ is the key parameter correlating with the energy absorption capacity. To overcome the lower specific absorbed energy (SAE) in the DSC tube compared to that in the S-tube, the CF1263 carbon/ epoxy composite laminate was adopted and the corresponding SAE was 5.9 times higher than that of the aluminum one. Moreover, the influence of the number of corrugations on the crushing behaviors of the DSC tube was also digitalcommons.unl.edu M o z a f a r i e t a l . i n C o m p o s i t e s P a r t B 1 3 4 ( 2 0 1 8 ) 2 inspected. A minimal straight tube section was suggested for a controllable smooth crushing behavior regardless of its advantage in SAE. This work might shed light on designing future thin-walled energy absorber devices with better control of crushing behaviors for minimal injuries and damages.
