“…Experimental research on PWCs seems to be more limited, and published research has investigated the effect of the type of woven fabric, thickness of the laminate, undulation, gaps and continuity of the yarns, the geometry of the weave, the stacking sequence, the relative position between plies and off-axial loading. 4,29,[31][32][33][34][35][36][37] Simulation of textile composites such as plain weave and twill or satin weaves is challenging, because the simplified assumptions of common micromechanical methods remain no longer valid. 20 In order to take advantage of both analytical and numerical methods, some semi-analytical approaches have been proposed to improve the efficiency over purely numerical methods.…”

The digital image correlation (DIC) technique is employed to measure the strain fields and the five independent elastic material constants of a glass/vinyl ester plain weave laminated composite. Transverse (through-thickness) tensile and Iosipescu shear properties were measured using thick (∼19 mm) laminates, and the strain fields were compared against those predicted by a homogenized linear elastic finite element analysis. DIC reveals that the strain fields of the laminates may present heterogeneous zones, which are attributed to the heterogeneous nature of the woven fabric architecture. Homogenization of the DIC strain fields to produce two-dimensional stress-strain plots yields average strains and elastic properties of the woven composite which can be similar to those measured by conventional (localized) strain gages. Important differences were found for the transverse tensile and Iosipescu shear tests, where differences of 26.4%, 28.6% and 11.9% were obtained for the measured transverse elastic modulus ( Ez), in-plane shear modulus ( Gxy) and transverse shear modulus ( Gxz), respectively.

“…During recent decades many researchers have studied buckling and delamination behavior of composite plates. 1–20 Chai et al 1 performed a theoretical and fundamental study on one dimensional delamination bucking of laminated plates using beam-column delamination theory. They showed that the dimensions of the delamination, the load at which it is introduced and the fracture energy influences the buckling delamination behavior of laminated plate.…”

In the present study, the buckling behavior of delaminated plate in woven fabric composite laminates was studied. For this purpose, at first, the structure of woven fabrics was defined as shape functions. Then, the continuous analysis was used to study the bucking of delaminated plates. Based on the Rayleigh–Ritz method, the related formulations were developed to predict the critical buckling load of composite laminates. Three types of woven fabrics (viz. Plain, Twill, and Satin architecture) were used as reinforcements for polyester composites. The 8-ply laminated composites were fabricated using Vacuum Infusion Process (VIP). The results of buckling test showed that the critical buckling loads of laminates reinforced with Plain, Twill, and Satin woven fabrics are 1.35, 1.12, and 1.48 kN, respectively. Also, the results of analytical method are compared with experimental results and those achieved by the finite element method of analysis using ABAQUS software. Compared with experimental results, the maximum error of analytical and FE models is about 17% and 10%, respectively.

A simple technique for fiber reorientation in laminated and woven composite material is presented in this paper. This technique is suitable for nonlinear finite element simulations of composite structure failure. The developed technique is implemented in the nonlinear explicit finite element code DYNA3D to demonstrate the effect of the fiber reorientation on the behavior of laminated composite materials in crash simulations. The same technique is added to a woven fabric composite material micromechanical model to account for the change of the model geometry.Using an incremental approach programmed in the MATLAB software, the stiffness change of the woven composite micromechanical model as a function of the yarn tow reorientation is investigated. Significant change in the elastic properties is observed as a result of the scissoring effect and fiber reorientation in woven fabric composites.KEY WORDS: fiber reorientation in composite materials, computational micromechanical material model, woven fabric composites, textile composites, and nonlinear finite element analysis.
