“…Both studies concluded that unstable delamination propagation was often caused by mode-I fracture while mode-II fracture led to stable delamination growth in the cases examined. Chirica and Beznea [6] developed an FE model to predict the buckling behaviour of composite plates with a central elliptical delamination. They found that the aspect ratio of the delamination had a significant effect on the relationship between in-plane loading and displacement.…”

A 3D finite element model using cohesive elements and continuum (bulk) material damage models was developed to examine the progressive damage and failure behaviour of Glare R Fibre Metal Laminate (FML) specimens subjected to in-plane compressive loading. The specimens contained internal 'splice' and 'doubler' features and were either pristine or contained simulated manufacturing defects in the form of artificial delaminations. The initiation and growth of delaminations at the inter-laminar interfaces, damage in the glass fibre reinforced polymer (GFRP) plies, ductile damage in the resin pockets (FM94 epoxy) and the onset of plasticity in the metal layers were examined. Geometric imperfections and load eccentricity were incorporated in an explicit dynamic nonlinear analysis implemented in the software Abaqus/Explicit. A series of buckling tests on specimens with and without artificial delaminations were conducted for validation, which are described in detail in a companion paper. Tests were monitored using Digital Image Correlation (DIC) for visualisation of full-field displacements and strains whilst Acoustic Emission (AE) monitoring enabled detection and localisation of the onset and progression of damage. Results for 'Glare 4B' specimens incorporating longitudinal and transverse delaminations into both splice and doubler geometries are presented. These results revealed that in order for the finite element analyses to be validated, all the damage and plasticity mechanisms * Corresponding author.

“…Today, fibre-reinforced composite materials are applied everywhere in the industry: such as cars, air planes, ships, space vehicles, sport equipments (Gohardani and Hammond, 2013;Giannis and Hansen, 2010;Chirica and Beznea, 2011). The heterogeneous behaviour of these materials makes their damage analysis very important (Hills et al, 1996;Adams et al, 2000;Davidson et al, 2010;De Moura et al, 2011).…”

a b s t r a c tIn this work we analyse the buckling process of composite plates with trough-the-width delamination and straight crack front applying uniaxial compression. Local, global and mixed mode buckling cases are considered. The novel part of this work is that the distribution of the resulting in-plane forces is taken into account for the analysis of the buckling of the delaminated plate portions. For determining the behaviour of the delaminated plate with respect to the external compression, first an analytical method is given for determining the global critical loads. Second the local critical forces are determined using a finite element model. For this analysis a semi-discrete element was developed for the delaminated plate portions. The analysis was carried out using the method of harmonic balance because of the distribution of the in-plane forces along the delamination front. The buckling process of the plate with respect to the axial compression is determined from a displacement controlled model.
