“…The multiscale projection method by Löhnert and Belytschko [2] simulated fracture and crack propagation using XFEM to investigate the effect of macrocracks and microcracks interactions leading to damage. The adaptive progressive damage modelling technique by Labeas et al [3] was used for the prediction of damage initiation and evolution in composite structures. Their approach combines a progressive damage modelling technique with the submodeling method.…”

“…The present technique is different from the ones used in other works. A more accurate homogenization scheme is used than the simplified procedure of averaging the local engineering constants performed by Labeas et al [3]. Another advantage of the present approach is that it is non-intrusive in the sense that it can be directly combined with standardly available commercial finite element codes.…”

Composite laminate stiffened panels are often used in aircraft fuselage design because of their favourable properties. To assess the failure load of these thin-walled structures and to exploit their reserves, a reliable simulation capability for their postbuckling behaviour is often necessary. To perform a realistic failure analysis and to accurately detect final collapse, material degradation should be considered. Global-local approaches are computationally efficient techniques to perform a progressive failure analysis and to examine localized damaged areas in detail. In this paper, a two-way coupling global-local approach is presented, including a combination of different damage modes, such as matrix cracking, fiber damage and skin-stringer debonding. An accurate exchange of information concerning the damage state between global and refined local models is performed. From the global to the local model, the displacements are transferred through a submodeling procedure. Afterwards, the degraded material properties obtained from the local model analysis are returned to the global model with a special mapping technique that accounts for the different mesh sizes at the two levels. The two-way coupling procedure is applied to the progressive failure analysis of a one-stringer composite panel loaded in compression. Finally, the numerical results of the procedure are compared with experimental results.

“…In contrast, during a twoway coupling, the information is exchanged in both directions, accounting for interactions of global and local eects. To cite a few of the recent globallocal approaches, the multiscale projection method by L ohnert and Belytischko [11] and the adaptive progressive damage modeling technique by Labeas et al [12] are to mentioned. Two-way loose coupling methods [13,14,15] provide a promising way to analyze various types of nonlinear structural analysis problems in an ecient way.…”

A two-way coupling global-local nite element approach, which has demonstrated its potential on the basis of representative test cases in earlier work, is used for the progressive failure analysis of large stiened composite panels. In order to realize the capability of the approach to analyze larger panels, the eciency of the analysis is enhanced, and improved rules for the choice of the size of local models are developed. The potential to carry out a progressive failure analysis for large stiened panels is illustrated rstly through the analysis of a two-stringer panel with a local defect, in which the adjusted rules to dene the local models are applied, and subsequently concretized by applying the approach to a large stiened composite panel with ve stringers. A comparison between the results of the global-local coupling analysis and the shell element reference analysis are demonstrated and the results are discussed. The results of the numerical analyses of the large panel are also compared with experimental results available.

Interference-fit technology has a wide effect on the strength and fatigue life of composite structures. The damage around the hole may accelerate the structure failure. In this paper, a progressive damage model is developed to predict the response of interference-fit pin-loaded composite laminates during the installation and loading process with the ABAQUS subroutine user-define-field (USDFLD). The model takes contact at the pin–hole interface, the nonlinear shear stress–strain relationship and the property progressive damage into consideration. The loading procedure is separated into two parts: (a) installing the Hi-Lok pin. (b) Applying the tensile load. To predict progressive failure, the mixed failure criteria combining Hashin criteria and the maximum stress failure criteria, and the Camanho and Matthews degradation rules are conducted. The insertion load, stress and damage around the hole, load–displacement curve, and the bearing strength are predicted. A series of experiments have also been performed and the rationality of the model is testified. The parametric study is also made to analyze the effect of fit conditions on insertion load, damage, and load–displacement curve.
