Abstract The aim of this work is to investigate the effect of the loading rate on the crack growth behavior in carbon fiber reinforced polymer composites, under mode I monotonic tensile loading. For such objective, inter-laminar fracture toughness tests were performed on double cantilever beam (DCB) specimens, according to the ASTM-D5528 standard. The initial crack tip opening displacement (CTOD) was obtained by employing the digital image correlation (DIC) technique. Then, the strain energy rel...

Abstract Virtual crack closure technique (VCCT), cohesive zone modeling (CZM) and extended finite element method (XFEM) are three well-known numerical methods frequently used for crack propagation modeling. It is often questioned by new researchers and engineers: which method is more appropriate for modeling of delamination propagation in composites? In this study, advantages, limitations, and challenges of each method are discussed with the goal of finding a suitable and cost-effective solution...

Abstract Digital-image correlation (DIC) is used to analyze an adhesively-bonded double-cantilever beam (DCB), and to determine the traction-separation law for a cohesive-zone model. The issues involved with how to extract useful information from the digital data of DIC are addressed. In addition, DIC is used to explore how the cohesive zone evolves, and to determine how the elastic arms deform in response to the loading and to the adhesive. The results of these observations are compared to nume...

Abstract In this article, the effect of the tensile loading rate has been investigated on mechanical properties and failure mechanisms in open-hole carbon fiber reinforced polymer composites. For this objective, acoustic emission signals on standard specimens under tensile loading were acquired and analyzed by the wavelet packet transform (WPT) and the fuzzy C-Means (FCM) methods. Tensile tests were also performed on pure resin, pure fiber and composite samples, at different loading rates. Obtai...

Abstract The fracture of an adhesively bonded joint is a complicated process of crack nucleation and propagation. In this work, a method for modelling the fracture process with separate nucleation and propagation phases is presented. The method combines the virtual crack closure technique (VCCT) with the cohesive zone modelling (CZM) on the finite element basis to take into account the development of fracture toughness. The method is applied to simulate a double cantilever beam (DCB) test as an ...

Abstract In the present research, damage mechanisms in the open-hole laminated carbon/epoxy composite have been investigated using the acoustic emission method. For such objective, standard specimens, made of the pure resin, the pure fiber and composites, were tested under tensile conditions, at a constant loading rate. Then, the clustering effect was studied in order to know which damages (debonding, fiber pull-out, delamination, matrix cracking and fiber breakage defects) occurred in the mater...

Abstract The quality of bonding between the liner and composite shell of a type IV pressure vessel is a crucial point to prevent the leakage of this vessel subjected to fill and refill cycles. In the present research, acid etching was used for surface treatment of a plastic liner to increase the bonding strength. The numerical and experimental study was conducted to investigate the effect of surface treatment duration on the adhesive bonding of E-glass/epoxy composites to the polyethylene (PE) l...

Abstract This study proposes a simple and accurate data reduction scheme for the wedge loaded double cantilever beam (DCB) specimen. The effects of axial loading applied by wedges were considered for the evaluation of mode I energy release rate. Furthermore, a methodology for the determination of crack length during the tests was proposed. The presented method was verified by both finite-element (FE) analyses and fracture toughness tests. The results of the FE analyses showed that the mode I ene...

Abstract In this paper, the role of interface fiber angle on the bridging traction of double cantilever beam (DCB) specimens is investigated experimentally. In order to eliminate the effect of the remote ply orientation on the bridging traction during delamination initiation and propagation, DCB specimens with stacking sequences of [0 11 /θ//0 12 ] where θ = 0, 30, 45 and 90 were considered. An experimental test set-up was established for measuring the Initial crack tip opening displacement (ICT...

Abstract Structural components are often subjected to complex multiaxial loading conditions. The study of fatigue cracks under such conditions is not easy from an experimental point of view and most works tend to focus more on the simpler but less realistic case of uni-axial loading. Consequently, there are many uncertainties related to the load sequence effect that is now well known and is not normally incorporated into the growth models. The current work presents a new methodology for evaluati...
