“…For this reason, the geometry of fabrics has received a great deal of attention by researchers. 21,[26][27][28][29][30] Alif et al 26 concentrated on the effect of weave pattern on mode I of delamination. They defined an index, named weave index, n g , which indicates the interlacing counts between the warp and weft yarns and found that the delamination resistance increased with the increase in weave index.…”

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.

“…Hence, they are widely applied to terrestrial and aerospace structures [1]. However, an inflated beam is a typical thin-wall structure and instability phenomena, including global buckling, local wrinkling or both, may easily occur [2,3]. Investigations on the instability phenomena of these structures can be separated into two categories: global buckling analysis and local wrinkling analysis.…”

The interactive bending wrinkling behaviour of inflated beams

A model is proposed based on a Fourier series method to analyse the interactive bending wrinkling behaviour of inflated beams. The whole wrinkling evolution is tracked and divided into three stages by identifying the bifurcations of the equilibrium path. The critical wrinkling and failure moments of the inflated beam can then be predicted. The global-local interactive buckling pattern is elucidated by the proposed theoretical model and also verified by non-contact experimental tests. The effects of geometric parameters, internal pressure and boundary conditions on the buckling of inflated beams are investigated finally. The results reveal that the interactive buckling characteristics of an inflated beam under bending are more sensitive to the dimensions of the structure and boundary conditions. We find that for beams which are simply supported at both ends or clamped and simply supported, boundary conditions may prevent the wrinkling formation. The results provide significant support for our understanding of the bending wrinkling behaviour of inflated beams.

“…The bending stiffness including expression of wrinkling factor is substituted into the deflection differential equation, and then the slope and deflection equation of the inflatable beam is deduced by integrating the deflection differential equation. Nguyen et al [16] analyzed the linear eigen and nonlinear buckling analysis of an inflatable beam made of orthotropic technical textiles. The nonlinear finite element solutions were investigated by using the straightforward Newton iteration with the adaptive load stepping for tracing the load-deflection response of the beam.…”

The load bearing capacity of an ETFE (ethylene-tetra-fluoro-ethylene) inflatable tube is tested in this paper, and a comparative study of two wrinkling theories, the bifurcation theory and the tension field theory, is carried out for wrinkling analysis of the ETFE inflatable tube. Results obtained from the bifurcation theory and experiment reveal the limitations of tension field theory on the wrinkling analysis. The load-displacement curves of inflatable beams under bending load are obtained and compared with the experimental results; curves obtained using the bifurcation theory show coincidence with experimental curves, but the curves obtained using the tension field theory have noticeable deviations between calculated and experimental results.
