Light fibrous materials composed of elastic fibers display a non-linear elastic behavior, where the non-linearity is due to the increase in the number of contacts between fibers under compression. Testing glass wool under compression up to 95% shows such a strongly non-linear behavior. A model is proposed to account for the divergence of the compressive stress σ as the strain ε approaches a threshold compression , with . Quantitative analysis of the experimental data on glass wool is fully consistent with this result.
