“…However, in practical applications, the impactor's trajectory of incidence can be arbitrary relative to the target. Although numerous works are done on studying the oblique impact between bodies incorporating different contact models, [169][170][171][172][173][174][175] only a few literatures are available on OLVI on laminated structures and GLAREs in particular, [176][177][178][179][180] investigating their dynamic responses and the associated interfacial delamination. Neogi et al 181 investigated the low-velocity impact behaviour of a simply supported composite hypar shell roof under oblique impact, considering modified Hertzian contact law for different impact velocities and impact angles.…”

Even though several works are available on the analysis of low-velocity impact (LVI) on fibre metal laminates (FMLs), there is still scope for a better understanding of the complexities associated with their analysis, making it an important area of research. Therefore, it is essential to compile and present the state-of-the-art research in this area to make the critical information available in one paper, facilitating future research. This paper thus covers the detailed review of the articles published on the LVI response of fibre metal laminates (FMLs) based on experimental, numerical and analytical approaches and the associated damage mechanisms under different impact conditions. The discussions can be mainly categorized into two broad groups, namely geometrical and material-based parameters, which significantly influence the structural response of FMLs upon impact. Additionally, the paper compares various numerical techniques reported to model the impact behaviour of FMLs, along with an overview of analytical models. Based on the manufacturing techniques and material constituents of FMLs, the paper discusses feasible methods of improving the performance of impact-prone structures. The exhaustive review of the literature finally concludes that there are scopes of investigating some of the important and relevant areas related to LVI of FMLs like the influence of relative mass of impactor and target and accurate determination of contact stiffness for accurate estimation of interface delamination. Investigating the LVI performance of advanced sandwich structures with FML facesheets is a potential area of research in this direction.

“…The existing reports on the calculation methods of contact dynamic response are mainly divided into the following categories, finite difference-Newmark method [26], the two-step perturbation method [27,28], differential quadrature method (DQM) [29], Fourier expansion and Galerkin truncation [30][31][32][33], Ritz method [34][35][36] and finite element method [37,38]. The stochastic sensitivity analysis was dealt with of functionally graded material (FGM) plates subjected to low-velocity impact to identify the most influential parameters in the respective analyses [39].…”

Fluid-conveying nanotubes play key roles in micro-nano electromechanical systems. The contact dynamic response and stress field of the fluid-conveying graphene reinforced composite (GRC) nanotube under lateral low-velocity impact are studied. The size-dependent models considering slip flow, nonlocal stress and strain gradient effect are established. The governing equations of flow-inducing post buckling and contact vibration are derived based on a refined beam theory, in which the post-buckling equilibrium provides the initial configuration for the impact vibration analysis. A computation mode of two-step perturbation-Galerkin truncation-Runge-Kutta method is developed to study the contact dynamic responses. Through the convergence analysis, the truncation terms required to ensure the accuracy are obtained. The contact force curves and the midspan displacement time history curves are acquired, and the dynamic snap-through instability behaviors of the nanotube in the flow-inducing post-buckling state are revealed. Also, the stress field in the impact process is obtained to provide theoretical results to guide the strength design. Numerical results reveal the dual influence law of nonlocal stress and strain gradient on the contact dynamic response and stress field and provide the flow velocity range sensitive to the nano effects.
