Buckling Analysis of Woven Fabric Under Simple Shear Along Arbitrary Directions

Abstract

This work continues our study of woven fabric buckling and provides generally analytical results on the buckling of a woven fabric sheet subjected to simple shear along the direction making an angle, θ(0° ≤ θ < 90°) say, to the warp. The buckling direction is related to the angle 0 and the critical amount of shear. As an illustration, the curve of the buckling direction angle versus the amount of shear for θ = 30° is plotted. Out-of- plane fabric buckling is possible, and only a flexural buckling mode can occur. The buckling condition for the flexural mode is also obtained and, as an illustration, a curve for 0 = 30° is plotted. This work also provides foundations for numerical methods to simulate KES shear buckling for fabric.

Nonlinear Buckling of Woven Fabrics Part II: Recovery from Buckling and Experimental Verification

“…For each value of , the values for λ 2 are systematically varied from 0, for the model proposed by Grosberg and Swani [2], to 0.2, 0.5, and 0.8 for the bilinear model. The numerical results obtained from the present model are consistent and appear realistic in terms of the theoretical and experimental behavior previously reported by various authors [2,[6][7][8][9][10][11][12][13]. As expected, at a constant value of , in general, the recovery from buckling, at the same percentage compression level, gradually increases with a concomitant decrease in total hysteresis as the value of λ 2 increases from 0, for the model proposed by Grosberg and Swani [2] to 0.2, 0.5, and 0.8 for our model.…”

Mechanical properties and buckling analysis of woven fabric

“…Fabric sheets are very thin, and the theory of thin plates can be adopted to simulate deformations of the fabric under uniaxial force tension, compression force or simple shear that cause a buckling. 22 Figure 2 illustrates the fabric sample clamped at both ends and under compression of a uniformly distributed load.…”

Fabric Handle and Its Basic Mechanical Properties

“…Alimaa et al [87] studied the effects of yarn bending and fabric structure on the bending properties of plain and rib knitted fabrics. Zhang and Xu [88] analyzed buckling of woven fabric under simple shear along arbitrary directions. Kang et al [89] studied fabric buckling based on nonlinear bending properties.…”
