“…A slightly lower value is obtained for the unit cell with identical topology using DFCA. Since the actual cross-section area in the loading direction is unavailable from the literature, the corrected cross-sectional area, A e , is calculated to determine the nominal stress σ x , according to equation (15). A and v f are the nominal area and overall fiber volume fraction from DFCA, whereas A e and v e f are those from the experimental data.…”

“…27 Bergan used a CDM model with cohesive zone elements to model damage inside yarns and on yarn-matrix interfaces, while matrix damage is accounted for by plasticity. 15 Saleh et al proposed a micro-mechanical model to simulate tensile response of woven composites using damage evolution laws governed by material parameters. 28 Bogdanovich et al used the 3D Mosaic concept to represent the woven composite structure as an assembly of an arbitrary number of distinct homogeneous anisotropic material blocks.…”

“…This includes the non-conformal meshing strategies like voxelbased mesh generation techniques [10][11][12] as well as the conformal meshing strategies. [13][14][15][16] In voxel-based meshing techniques, zigzag yarn boundaries could lead to stress concentrations at sharp edges, causing interlocks. Although these methods have been found to generate good results for stiffness, their capability to predict progressive damage is not well demonstrated.…”

A progressive damage model is presented to investigate the damage and failure behaviors of woven composites. The conformal finite element mesh for the woven composites, used for this analysis, is generated using fabric micro-geometry from DFCA (Digital Element Approach (DEA) Fabric and Composite Analyzer, Kansas State University). The mesh generation strategy is discussed briefly – it does not make any idealized assumptions about yarn geometry and thus can be used for any woven composite micro-geometry. The woven composite domain consists of homogeneous and transversely isotropic yarns, and the surrounding homogeneous isotropic matrix. A recursive stiffness reduction method that allows for combined failure modes is employed to model progressive damage behavior. Two different fabric micro-geometries are studied: a 2D plain-weave laminate and a 3D orthogonal-weave unit cell. To support the validity of the proposed model, numerical results for the mechanical behavior of the two cases are discussed and compared with numerical predictions in literature and available experimental data.

“…Although TexGen has many advantages, there is still a lack of complete automation tools for modeling, simulation and post-processing of woven composite. In addition, fabric modeling and analysis programs such as WiseTex, 19 CompDam, 20 DFCA, 21 and NASMAT 22 have been developed for multi-scale analysis. However, computational cost can be exorbitant as many of the models contain upwards of hundreds of thousands, or even millions, of degrees of freedom to admit the necessary geometric complexity.…”

This work presents a beam element approach for the modeling and high-efficiency simulation of mechanical properties of 2.5D woven composite. For the beam element model, a technical scheme for the parametric modeling of 2.5D woven fabrics was produced. Considering the constraint relationship between the matrix and the fibers, we proposed a method for creating matrix beam elements. Then, a beam element solver was compiled to simulate the mechanical properties of the 2.5D woven composite. Meso-scale analysis of curved shallow-crossing linking 2.5D woven composite using the proposed model obtained the accurate tensile modulus. Full-scale analysis was implemented to simulate bending behavior of straight shallow-crossing linking 2.5D woven composite, and the simulation results agreed well with the experimental results. The above analysis could automatically complete modeling, analysis and post-processing in a relatively short time, reflecting the efficiency advantages of the method in this paper.

“…Some models have been developed to investigate the effects of damage at the various length scales present in 3D woven composites [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. However, when looking at the broader 3D woven-composite modeling literature, the trend is to use highly-refined finite element models of the woven architecture at a single scale [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ], and multiscale models are generally not employed due to prohibitive computational costs. As a result of the high computational demand for high-fidelity finite element models, particularly in the context of progressive failure analysis, it is currently challenging to perform sensitivity or optimization analyses for 3D woven composites based on this approach.…”

Multiscale Progressive Failure Analysis of 3D Woven Composites

Application of three-dimensional (3D) woven composites is growing as an alternative to the use of ply-based composite materials. However, the design, analysis, modeling, and optimization of these materials is more challenging due to their complex and inherently multiscale geometries. Herein, a multiscale modeling procedure, based on efficient, semi-analytical micromechanical theories rather than the traditional finite element approach, is presented and applied to a 3D woven carbon–epoxy composite. A crack-band progressive damage model was employed for the matrix constituent to capture the globally observed nonlinear response. Realistic microstructural dimensions and tow-fiber volume fractions were determined from detailed X-ray computed tomography (CT) and scanning electron microscopy data. Pre-existing binder-tow disbonds and weft-tow waviness, observed in X-ray CT scans of the composite, were also included in the model. The results were compared with experimental data for the in-plane tensile and shear behavior of the composite. The tensile predictions exhibited good correlations with the test data. While the model was able to capture the less brittle nature of the in-plane shear response, quantitative measures were underpredicted to some degree.
