“…Although the through thickness strain rate was not measured it is expected to be higher than the in-plane strain rate. Similar observations were made by Chan et al [19] for the ballistic impact problem and by LeBlanc et al for shock loading of flat composite plates [25]. Figure 11 illustrates several key points.…”

The dynamic response and damage evolution of composite materials subjected to underwater explosive loading has been studied. The study utilizes both experimental and numerical techniques to aid in the understanding of the behavior of these materials under shock loading conditions. The objective of the project is to develop a better understanding of the response of composite materials when subjected to shock loading conditions leading to more efficiently designed structures. The focus of the work is on performing high fidelity experiments under controlled shock loading and corresponding finite element simulations of the experiments.The work is divided into three phases, each of which build and expand upon the preceding work.In the first phase of the research the transient response and development of damage mechanisms of E-Glass / Epoxy composite plates is studied. The plates are bi-axial laminates consisting of a non-woven, parallel fiber construction, and are round, flat disks. The work consists of experiments, utilizing a water filled conical shock tube and computational simulations, utilizing the commercially available LS-DYNA finite element code. Two series of experiments have been performed and simulated: (1) a reduced energy series which allowed for the use of strain gages and (2) a series with increased energy which imparted material damage.The strain data obtained from the reduced energy experiments and the corresponding simulations are correlated using the Russell Error measure, a mathematical technique which evaluates the differences in two transient data sets by quantifying the variation in magnitude and phase. It is shown that there is a high level of correlation between the experiments and the simulations when using this measure. Additionally the extent of the damage, including the individual mechanisms, from the high energy experiments and simulations are compared and show good agreement.The objective of the second phase of the project was to increase the geometrical complexity of the composite plates by shifting from flat to curved mid-sections. The plates utilized in the second part of the study are E-Glass / Vinyl Ester, 0/90 biaxial laminates. The water filled conical shock tube is utilized to impart shock loading to the plates. Computational finite element simulations are performed with the LS-DYNA finite element code. The transient response of the plates was measured using a three-dimensional (3D) Digital Image Correlation (DIC) system, which included high speed photography and specialized post processing software.This ultra high speed system records full field shape and displacement profiles in real time. The transient response of the plates is compared to the simulation results using both point-wise time histories as well as full field deformation profiles. The DIC data and the computational results show a high level of correlation using the Russell Error measure.The third phase of the project investigates the relative response of three different laminate constructions. The objective...

“…Each mode is governed by the component of the stress vector associated with the failure plane by a quadratic equation. There are several expressions of Hashin criteria [4,32], in this work the three-dimensional formulation described in Hashin [4] was used. The formulation of both criteria is detailed below: -Fibre tension: the formulation of Hou and Hashin criteria is the same.…”

“…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.

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.
