A mathematical model is presented for the buckling of fabric under combined shear and tensile forces. This model takes account of the anisotropic characteristics of the fabric in terms of the flexural rigidities in the warp and weft directions, its corresponding Poisson's ratios, the shear modulus, and the width to height ratio of the rectangular specimen. Numerical solutions show that the critical shear force at which buckling starts and the number of buckles increase with increasing pre-tension. Furthermore, as the height or width of the rectangular specimen decreases, the critical shear force increases. For most fabrics where the flexural rigidity in the warp direction is higher than that in the weft direction, the results suggest that during tailoring, it is beneficial to orient the fabric so that the tension is in the warp direction to reduce the possibility of shear buckling in the garment.
