“…All elements of the XFEM-enriched regions have the former size, while the latter size is used for the elements between the enriched regions. Mesh sensitivity for XFEM solution was studied in [25]. For convergence of the model, viscous regularization is applied to stabilize the response during damage.…”

“…Together with the traction-free cohesive surfaces in the neighboring elements a continuous surface can form, which is referred to as a "traction-free crack". In [25], the reader can find a detailed discussion on identification of cracks in XFEM calculations. The predicted crack density at progressive simulation stages is calculated based on the traction free cracks.…”

“…This multiscale computational approach [21] relies on already developed models for each individual scale. For example, the transverse cracking (in the absence of voids) can be modeled using fracture mechanics approach [22] or eXtended Finite Element Method (XFEM) [23][24][25].

Voids are an important type of manufacturing defects in fiber-reinforced composites. Matrix cracking is sensitive to the presence of voids. Although this cracking occurs at the ply scale, its dynamics is strongly affected by ply's microstructure, in particular, fiber distribution, fiber content, and the presence of voids. In the current study, a computational approach to simulate the influence of intra-laminar voids on cracking in composite laminates is developed. The approach combines finite element models of two scales: a micro-scale model, where the fibers and voids are modeled explicitly, and a meso-scale model, where the cracking phenomenon is captured on the ply scale. The micro-scale model, incorporating plasticity and damage in the matrix, provides input for the meso-scale model, which simulates the progressive cracking by means of the extended finite element method. The methodology is applied to investigate the effect of voids on the density of transverse cracks in cross-ply laminates in function of the quasi-static tensile load. Different sizes and contents of voids, which are chosen based on experimental micro-computed tomography data, are simulated. The numerical experiments show that the presence of voids leads to earlier start of the cracking, with the crack density evolution less sensitive to voids.

Polymeric composites are used worldwide due to their enhanced applications in various sectors such as automotive, defense, aerospace, marine, and many others. Its lightweight and high‐strength applications make it convenient to use in high‐security fields such as defense and aerospace. Thus, it is essential to characterize composite materials for product development. Numerical simulation of composites has advantages over experimental characterization. The paper presents the mechanical behavior of polymer textile composites, employing geometrical modeling and a numerical simulation approach, under several loading conditions such as tension, compression, flexural, and impact loading. Failure mechanisms are also discussed with different failure modes and damage criterions. This review paper is limited to high‐strength fibers, such as carbon, Kevlar, and Glass fibers in unidirectional and woven formation. Various test specimens used in mechanical characterizations are presented with significant research summaries. Classification charts are also provided for a better understanding of the numerical simulation approach for characterizing the mechanical behavior.
