“…Some authors suggest that the specific energy‐absorption capability of thin laminates subjected to high velocity surpasses than that of thick laminates [6]. This inspired the use of multiple thin laminate plates to protect against a high‐velocity impact, although there are some discrepancies about whether a layered composite structure with or without spacing is better than a monolithic one [7].…”

Behavior of sandwich structures and spaced plates subjected to high‐velocity impacts

This work evaluates the behavior of sandwich and spaced plates subjected to high-velocity impacts. The sandwich structures were made of glass/polyester face-sheet and a PVC foam core. The spaced plates were made of two plates of the same material of the sandwich face-sheet at a distance equal to the core thickness. The residual velocity, the ballistic limit, and the damage area were selected to compare the response of both structures. The residual velocity and ballistic limit was very similar in both cases. Nevertheless, the damage area of sandwich structures and spaced plates differed due to the dissimilar properties between the sandwich core and the air inside of the spaced plates. An analytical model, based on energy criteria, was applied to estimate the residual velocity of the projectile, the absorbed energy by each facesheet, and the ballistic limit in the spaced plates.

“…[17][18][19][20][21][22][23][24][25][26] Ballistic penetration resistance of a target-projectile pair can be quantified by experimentally determining the ballistic limit velocity (V 50 ) and the ballistic limit energy (E 50 = (1=2)m P V 2 50 ). 27 Penetration resistance can also be quantified by the penetration resistance force acting on the projectile as a function of time and by studying the projectile dynamics which will require the use of an explicit finite element analysis (FEA) procedure.…”

The effect of support spans on single-hit ballistic limit and the effect of pre-existing ballistic damage on multi-hit ballistic limit for two S-2 glass/SC15 composite laminate thicknesses (i.e. 13.6 mm and 20.5 mm) using 0.50cal fragment simulating projectiles have been experimentally investigated in a companion paper. The main objective of this paper is to simulate and correlate the multi-hit ballistic experiments using finite element analyses. One multi-hit ballistic impact scenario on two different composite laminate thicknesses is considered in the present analyses. Finite element model of the impact scenario is developed using three-dimensional solid elements and are solved using LS-DYNA and the progressive composite damage model MAT162. The MAT162 properties and parameters of plain-weave S-2 glass/SC15 composites used in the present simulations were validated in our previous work. Multi-hit impact cases are simulated by sequentially impacting the composite laminate with five different fragment simulating projectiles at five different impact locations at an interval of 200 micro-seconds. Good correlations of ballistic limit velocities between experiments and finite element analyses are obtained. In addition, finite element analyses provided time histories of projectile and laminate dynamics, and damage evolution and interactions for the multi-hit impact cases. Detailed simulation results and comparison with the experiments are presented.

“…These impacts are particularly dangerous because they can drastically impair the mechanical behaviour of the structure after impact with little or no visible damage. The damage inflicted on a composite structure is a complex phenomenon due to the many parameters that could intervene [1] This problem has been studied by numerous researchers, primarily analysing the impact on plates [2][3][4][5][6][7][8], and less on beams [9][10][11]. However, better knowledge of the damage mechanisms and their evolution in composite beams is still necessary to improve the modelling of the damage for a better numerical assessment of their mechanical characteristics and thereby optimise their design.…”

“…Although both Hashin and Hou criteria are expressed in terms of stresses, they consider different failure mechanism and equations. Hashin criteria have been applied on laminated plates in low-velocity impacts [6,21,22] to estimate load history, and in high-velocity impacts to study the damage area and absorbed energy [4,7,8,23]. Chang-Chang and Hou criteria have also been applied in analysing the behaviour of composite laminated plates subjected to impact at low [2,24,25] and high velocities [11,26].…”

Hou and Hashin criteria were compared under dynamic conditions, analyzing the failure of beams subjected to low velocity impacts in a three point configuration. To accomplish this goal a progressive failure model was implemented in a finite element code to predict the failure modes (fibre tensile failure, fibre compressive failure, matrix cracking, matrix crushing, and delamination), considering both Hou and Hashin criteria. The experimental results, from tests conducted in a drop-weight tower and available in the literature, were used to validate the numerical model. This model, using both criteria, was used to analyse the failure modes of two lay-ups (unidirectional and crossply) tested in two experimental devices (drop-weight tower and split Hopkinson pressure bar). The main failure mechanisms in both laminate lay-ups were also identified.
