“…On the other hand, as the test is running further, delamination was observed between the composite layers. These failure signs are consistent with those recorded by Mahdi and Sebaey 94 for the crushed aramid/carbon hybrid composites and Alkhatib et al 95 for crushed carbon fiber-reinforced polymer and Kevlar fiber-reinforced polymer tubes.…”

This paper investigates the crashworthiness performance of square pipes with induced holes. Glass reinforced epoxy (GFRP) specimens were fabricated and tested under quasi-static axial crashing. Four design parameters were chosen, each at three levels, to calculate crashworthiness indicators. The design parameters are the hole diameter (d), the hole position to specimen length ratio (P/L), the number of holes and distribution (n), and crosshead speed (V). Taguchi technique has been adapted to get the optimum crashworthiness parameters. Experiments based on Taguchi’s orthogonal array with 9 experimental runs (L9) were performed. Optimal conditions with the maximum absorbed energy (U) and minimum initial peak force ([Formula: see text]) were determined. The main effects, signal to noise ratio (S/N), and analysis of variance (ANOVA) have been investigated. Results indicated that “V” followed by “d” are the highest influencing parameters on the values of “U” with a contribution of 49% and 43%, respectively. The dominant influencing parameter on the values of [Formula: see text] is “n” with a contribution of 94%. Finally, confirmation tests were carried out to validate the estimated model with respect to experimental results. The optimum U and [Formula: see text] of GFRP square pipes with circular cutouts were compared with those of non-porous specimens.

“…Many authors researched the crushing behaviour and capacity of radial corrugated geometries (Abdewi et al, 2008;Xiong et al, 2016) among many others. The study indicates that (Alkhatib et al, 2020) in the corrugated metal tubes was less than the value in the circular tubes, the first point in the loaddisplacement curve. The deformation mode in corrugated metallic tubes was more stable, too.…”

The axial crushing behaviour of tubes of different section shapes has been extensively investigated as they have an excellent energy absorption, but the thin walled corrugated tube structures have been designed to further improve their energy absorption performance. The study aims to analyze the effect of sinusoidal corrugations along cross section of the tube on peak force, energy absorption and specific energy absorption. In the present work the response surface methodology (RSM) using central composite design (CCD) has been used and simulation work is performed by using ANSYS workbench to explore the effects of geometrical parameters on the responses of constructing models.

“…In its formulation and during the loading, the damage of the material was a linear function of the distance between the two points which were initially in contact. When a critical opening was reached, the contact was being broken, and the bonded composite layers were converted into two separate surfaces with the regular surface-to-surface contact between them, see [ 23 ]. AUTOMATIC_SURFACE_TO_SURFACE was defined between the bullet and the composite plate since this contact can deal with the deformations resulting from the bullet impact.…”

“…Liu et al [ 17 ] have reduced ceramic and Kevlar layers’ thickness in ceramic ballistic plates for the same protection and lighter body armor. Alternatively, introducing small-scale energy absorption devices as a core in the armor plates and forming sandwich panels is a promising technique in the ballistic field [ 2 , 18 , 19 , 20 , 21 , 22 , 23 ].…”

In this paper, hybrid composite plates for ballistic protection were investigated experimentally and numerically, with a target to reduce the weight of currently used body armor inserts and, at the same time, satisfy the requirements of the National Institute of Justice’s (NIJ) ballistic protection standards. The current study has three phases to improve the ballistic plate’s energy absorption capability. The first phase is devoted to studying the effect of the material types, including three different fibers: carbon fiber, date palm fiber, and Kevlar fiber. The second phase is dedicated to studying the effect of hybridization within layers. The two previous phases’ results were analyzed to optimize the material based on the hybrid composite ballistic plate’s maximum energy absorption capability. The commercial finite element software package LS-DYNA was employed for numerical modeling and simulation. The hybrid composite ballistic plate could absorb more impact energy than the non-hybrid Kevlar plate with the same area density from the numerical simulation results. This study provides lighter-weight ballistic inserts with a high protection level, making movement easier for the wearer. The numerical results were verified by comparing results of a plate made of 40 layers of Kevlar with an actual ballistic test. The results indicated that the simulation results were conservative compared to the ballistic test.
