“…1,4 The influence of some of these parameters on the perforation of laminate plates has been studied. 2,3,[5][6][7][8][9][10] One of the main parameters affecting perforation is laminate thickness. An alternative and related parameter is the areal or surface density (density per square meter) of the laminate.…”

“…Several authors have studied the influence of these parameters on perforation velocity or the perforation-threshold energy of Kevlar-, carbon-and glass-fibre laminates. 2,[5][6][7]9,[11][12][13][14][15][16][17][18][19] For armour-grade laminates, a non-linear relationship between perforation-threshold energy and thickness has been suggested. 17 Zhu et al 5 studied the perforation response of [0/90] Kevlar/polyester laminates impacted by cylindro-conical projectiles.…”

This work analyses the influence that the areal density of a composite thin-plate, made of glass-fibre woven laminates and subjected to high-velocity impact, exerts on perforation-threshold energy, contact time, and energy-absorption mechanisms. The perforation-threshold energy increased with the areal density. Also, the contact time increased at impact energies above the perforation-threshold energy and decreased below this threshold. The main energyabsorption mechanisms at impact energies close to that causing perforation were found to be the deformation and failure of the fibres, regardless of the areal density. For higher impact energies, the main mechanisms were fibre failure and the energy absorbed by acceleration of the laminate.

“…Due to the orthogonality of composite laminates, some elements in the impact region will be more easily distorted during the simulations, which may lead to numerical instabilities or even calculation failure (Deka et al, 2008). In this study, element effective strain is used as the erosion criterion, similar approach has been adopted in the references (Grujicic et al, 2009;Bandaru et al, 2015Bandaru et al, , 2016.…”

A numerical material model for composite laminate, was developed and integrated into the nonlinear dynamic explicit finite element programs as a material user subroutine. This model coupling nonlinear state of equation (EOS), was a macro-mechanics model, which was used to simulate the major mechanical behaviors of composite laminate under high-velocity impact conditions. The basic theoretical framework of the developed material model was introduced. An inverse flyer plate simulation was conducted, which demonstrated the advantage of the developed model in characterizing the nonlinear shock response. The developed model and its implementation were validated through a classic ballistic impact issue, i.e. projectile impacting on Kevlar29/Phenolic laminate. The failure modes and ballistic limit velocity were analyzed, and a good agreement was achieved when comparing with the analytical and experimental results. The computational capacity of this model, for Kevlar/Epoxy laminates with different architectures, i.e. plainwoven and cross-plied laminates, was further evaluated and the residual velocity curves and damage cone were accurately predicted.

Abstract. A finite element model was developed to study the damage mechanisms of composite laminates under high velocity impact conditions. Modified Hashin failure criteria were used for the fiber breakage prediction. Cohesive elements were defined between two adjacent layers in the target laminate for the prediction of delamination initiation and propagation during the impact. The strain rate effects were also considered for the composite stiffness and strength. By using the developed finite element model, the ballistic limit, V L, for a composite laminated target can be calculated, which was validated by the test data in the public literature.
