“…Intralaminar damages, defined as matrix and fiber breakages, are generally predicted using progressive failure analysis (PFA). The PFA method includes three parts, such as the material constitutive model, the failure criteria, and the material degradation model 9 . The most utilized criteria are the Tsai‐Wu and Tsai‐Hill criteria, 10,11 the Hashin criteria, 12 and the Puck criterion 13 .…”

The fatigue behavior of composite materials is still a very challenging issue for the scientific community. So far, several numerical methodologies allow us to faithfully simulate the propagation of delamination due to fatigue. However, the reduction of material properties due to the applied cyclic load should be considered. The main objective of this work is to investigate the role of the material property degradation and the intralaminar damages on the propagation of delamination in composite laminates under fatigue loads. The numerical tool FT‐SMXB, based on the Paris Law and virtual crack closure technique, for the mimic of fatigue‐driven delamination, has been integrated with a user material subroutine, based on the generalized residual material property 7degradation model and the Hashin fatigue failure criteria. Typical aeronautical stiffened panel has been considered as test case. Matrix damages and strength degradation due to fatigue cycles have been found to influence the propagation of delamination.

“…Since then different kinds of damage formulations with a varying degree of complexity were developed for composite laminates and are applied in the recent literature. [15][16][17] Based on these damage formulations, the progressive fracture in composite laminates can be computed. The main focus is on the delamination of single composite layers [18][19][20] and on the matrix cracking.…”

The prerequisite to equip structures with in situ electrical health monitoring systems in a meaningful manner is to estimate potential damage locations. In this context, an analytical approach to model the spatial and temporal evolution of transverse inter-fibre fractures (IFF) is exemplified for [Formula: see text] cross-ply laminates under three-point bending. The model is based on the tensile load in the bottom 90°-layer. The effective stress is computed directly from the specimen displacement, whereas the strength is considered to be periodically distributed due to material inhomogeneities along the specimen. The continuous comparison between the sinusoidal strength function and the effective stress allows modelling progressive damage in form of IFF. A modified Hann window is used to consider their effect to the bottom 90°-layer. Experiments with the same configuration are performed and the observed IFF evolution is used to tune the model parameters in an optimisation procedure, e.g., the peak separation of the sinusoid and the length of the Hann window. The comparison between model and experiment shows a high level of agreement. The model is thus capable to reproduce experiments with minimal computational effort. This makes it highly suitable as input for electrical monitoring models that rely on the continuous damage evolution of the investigated structure. In its current form, the model is limited to the specified configuration. However, the simple analytical approach allows it to be easily adapted. It is furthermore shown that progressive composite damage in terms of spatial and temporal evolution can be accurately described using an analytical approach.

Three‐dimensional woven composites (3DWCs) are gradually used in marine, transportation, military, and other applications owing to their high interlayer properties, load‐bearing capacity, and good near‐net‐shape forming abilities. 3DWCs are often subjected to bending fatigue loads, which negatively affect the lives of structural parts. In this review, typical types of preform structures and their evolution characteristics are described, and the micro‐modeling methods for 3DWCs are discussed. The effect of the warp yarn paths on the bending properties and the preform structure on the bending fatigue properties of 3DWCs are summarized, and the application and current status of microstructural models in the study of bending fatigue properties are summarized. In addition, the bending fatigue mechanical properties, damage evolution process, and modes of failure in 3DWCs are discussed. The study status and development of the fatigue life models of the laminated composites and 3DWCs are summarized, and future research work is prospected. This review may be beneficial to preform structural design and contribute to the study bending fatigue properties of 3DWCs.Highlights The microstructural modeling methods for 3DWCs.
