Abstract

The deformation and damage micromechanisms of a glass-fiber non-woven felt were analyzed with a combination of experiments and simulations. Tensile tests were performed on unnotched and notched rectangular specimens to study the physical nature of damage. It was found that fracture was controlled by interbundle bond fracture followed by frictional sliding, leading to the localization of damage in a wide band. A random network model based on finite elements was developed in order to gain a better understanding of the experimental data. The simulations were in very good agreement with the data and contributed to explain features such as the effect of specimen dimensions on the strength of the material and its notch-insensitive behavior.
