Abstract
A fabric is a flexible material that it is highly affected by its own weight, which causes
large deflections. The relationship between the bending moment and the curvature is
nonlinear. This study presents a model for fabric buckling by considering the flexibility of
the fabric as well as its nonlinearity in bending. The bending rigidity of the fabric is
considered to be a function of its curvature to take into account the fabric’s nonlinear
bending properties. Based on Timoshenko’s elastica theory and the Bernoulli-Euler
theorem, geometric nonlinearity is also taken into account. Kawabata pure bending test
results are applied to the governing equation. The values from the model. are compared
with the experimental data. The results show a clear distinction from the linear model,
where the nonlinear method coincides well with the experimental values. From data
evaluated by the numerical analysis method, the critical buckling load is calculated.
