“…There is various published work that investigated the low-velocity impact of GFRP (glass fibre reinforced composites). Yarn-level finite element models combined with the experimental method were applied to analyse the damage behaviour and failure mode for carbon/glass hybridization through a low-velocity impact test [ 23 ]. A continuum damage mechanical model was developed and validated to present the effects of carbon/glass/basalt hybridization and fabric structure on the low-velocity impact resistance under different impact energy levels [ 13 ].…”

This study aims to investigate the influence of fibre orientation and varied incident energy levels on the impact-induced damage of S2/FM94, a kind of aerospace glass fibre epoxy/composite regularly used in aircraft components and often subjected to low-velocity impact loadings. Effects of varying parameters on the impact resistance behaviour and damage modes are evaluated experimentally and numerically. Laminates fabricated with four different fibre orientations 0/90/+45/−458s, 0/90/90/08s, +45/−4516s, and 032 were impacted using three energy levels. Experimental results showed that plates with unidirectional fibre orientation failed due to shear stresses, while no penetration occurred for the 0/90/90/08s and +45/−4516s plates due to the energy transfer back to the plate at the point of maximum displacement. The impact energy and resulting damage were modelled using Abaqus/Explicit. The Finite Element (FE) results could accurately predict the maximum impact load on the plates with an accuracy of 0.52% to 13%. The FE model was also able to predict the onset of damage initiation, evolution, and the subsequent reduction of the strength of the impacted laminates. The results obtained on the relationship of fibre geometry and varying incident impact energy on the impact damage modes can provide design guidance of S2/FM94 glass composites for aerospace applications where impact toughness is critical.

“…3D weaving technology is an effective approach to maintain structural stability within different layers of warp and weft yarns by introducing Z-yarns along the through-thickness direction to fabricate 3DOW architectures (Mouritz et al., 1999). From literatures of both experimental and numerical methods, it has been commonly realized that the 3DOW architecture (Midani et al., 2018, 2019) plays an essential effect on the impact-induced damage behaviors, for example, promoting the penetration resistance (Dewangan and Panigrahi, 2020, 2021; Ghosh and De, 2014; Jia et al., 2012; Turner et al., 2018), reducing delamination damage (Hart et al., 2017; Wu et al., 2020), and enhancing energy absorption capacity (Ahmed et al., 2020; Goud et al., 2020; Miao et al., 2019; Seltzer et al., 2013). Despite these potential benefits, there is currently a lack of knowledge about how damage develops in Ω-shape 3DOW under LVI.…”

Failure mechanism of complex profile component is always different from that of conventional plate counterpart due to the coupling effect of material and structure. In this work, the low-velocity impact (LVI) and compression after impact (CAI) behaviors of Ω-shape hybrid carbon/Kevlar 3 D orthogonal woven (3DOW) composite made for vehicle B-pillar were comprehensively studied by mechanical tests and mesoscale finite element (FE) analysis at component level, high-speed infrared (IR) thermal imaging, acoustic emission (AE) detection, and microscopic damage morphology characterization. It is found that a through-thickness stress concentration ring leads to high stress state and damage zone penetrating from the impact side to non-impact side along the ring path instead of at the lowest impactor position. The slope effect can not only help the stress conduction downward, but also inhibit the damage propagation from the impact side to the slope. Impact-induced cracks are concentrated around the R corners and extended along the axial direction of the specimen, forming the strip-shaped damage concentration zone along the upper eave of the slope. The Progressive Top-Down Crushing (PTDC) mode of compression after impact is due to the complex deformation process of each yarn such as squeezing, folding and eversion in the crushing process from the top of specimen. And the Middle Indentation Fracture (MIF) mode is the result of bending instability and abrupt fracture. This work presents a reference significance for the further development of composite strengthening components in vehicle bodywork.

“…ere is very little research addressing the impact force caused by wheel bounce and even less on the response and damage of the track slab under the impact force. e impact-induced damage is more concerned in the field of aerospace composite materials [10][11][12][13] and explosion mechanics [14,15]. In the existing studies of the impactinduced damage, the damage is usually evaluated from the energy point of view, by studying the mutual transmission of potential and kinetic energy.…”

During the running of a high-speed train, the wheel may bounce on the rail due to the track irregularity. The wheel bounce could generate a vertical impact, leading to the initiation and expansion of delamination between layers of the track structure. In this paper, the evolution of the interfacial damage and delamination subjected to the vertical impact is simulated using finite element analysis (FEA). In the FEA, a bilinear cohesive zone model (CZM) is adopted to simulate the interface between the track slab and the CA mortar layer. For different levels of impact energy, the contact force, vertical deformation, absorbed energy, area of interfacial damage, and area of delamination are calculated and compared. The effects of the tangential and normal stiffness of the interface on the distribution of interfacial damage and delamination are investigated. The results show that the contact force, vertical deformation, absorbed energy, area of interfacial damage, and area of delamination increase with the increase of the impact energy. The area of interfacial damage in the compression stage is closely related to the tangential stiffness, whereas the area of delamination depends on the normal stiffness. The normal stiffness that gives the largest area of delamination is recommended to be taken as the lower bound of the normal stiffness for both controlling the delamination and preventing an exceedance of the track irregularity limit.
