Failure Behavior of Plain Weave Fabric Laminates under On-Axis Uniaxial Tensile Loading: I—Analytical Predictions

Abstract

A two-dimensional woven fabric composite strength model is presented for the prediction of failure strength of two-dimensional orthogonal plain weave fabric laminates under on-axis uniaxial static tensile loading. Different stages of failure such as warp strand transverse failure, fill strand shear/transverse failure, pure matrix block failure and the failure of matrix and fiber in the fill strand in longitudinal tension are considered. Material and geometrical nonlinearities have been considered for predicting the stress-strain behavior. The studies were carried out for three idealized laminate configurations. The possible shift of layers with respect to each other along x-, Y- and -directions were considered for the laminates. A comprehensive experimental program was carried out on different material systems. A very good correlation is observed between the predicted and the experimental results.

An experimental study of failure initiation and propagation in 2D woven composites under compression

“…The relative positioning of adjacent layers with the same orientation, hereafter referred to as stacking, determines the number of coincident valleys and peaks between adjacent layers and, therefore, affects strongly the degree of nesting. Very few studies have discussed the effect of stacking (and resultant nesting) on the failure of woven composites [9][10][11][12][13]. Breiling and Adams [10], studying the compressive failure of a 5H satin carbon-epoxy, concluded that varying the stacking configuration (i.e.…”

Finite element modelling of damage progression in non-crimp fabric reinforced composites

“…The simulation outcomes at least provide a theoretical guide for the design of fabric architecture. Among the simulations, Representative Volume Element (RVE) model is the most commonly employed approach [11][12][13][14][15][16][17][18]. According to the fabric architecture, the composite structure is divided into repeated cells, representing the properties and the behaviour of the whole system.…”

“…To take the actual woven fabric geometry into account, Naik and Shembekar [12] applied the parallel or series models, section by section, for the RVE of a woven-fabric laminate. This approach considers the two-dimensional extent of the fabric and was used for the study of elastic and failure behaviour of plain woven fabric laminates by Naik and Shembekar [12] and Naik and Ganesh [13]. Recently, due to the fast development of high-speed computers, three-dimensional RVEs have been used to predict the overall properties and failure behaviour of fabric composites.…”

“…The damage prediction was based on the Maximum Stress criterion and selective stiffness reduction was applied after the damage was detected. Naik and Ganesh [13] considered the failure of woven composites loaded in the fill yarn direction. Different failure criteria were used for different constituents: Tsai-Wu failure criterion for the fill yarn, Maximum Strain criterion for the warp yarn and Maximum Stress criterion for the pure matrix material.…”

“…Different failure criteria were used for different constituents: Tsai-Wu failure criterion for the fill yarn, Maximum Strain criterion for the warp yarn and Maximum Stress criterion for the pure matrix material. Selective stiffness reduction was applied in the work of Naik and Ganesh [13]. Scida et al [15] used Tsai-Wu failure criterion to predict failure in the fill and warp yarns and the von Mises criterion to predict failure in the matrix.…”
