12th Fundamental Research Symposium, Oxford, 2001•bioresources.cnr.ncsu.eduThe stress-strain performance of 2D and 3D cellulose fibre networks was simulated using a
network model. A model network consists of bonded curled fibres placed at random in a cell.
The bonds show a stick-slip fracture behaviour. Results concerning the influence of network
density, fibre orientation and ductility of bonds on the stress–strain behaviour of a network
are given, and an example of fracture localization is provided.

Abstract
The stress-strain performance of 2D and 3D cellulose fibre networks was simulated using a network model. A model network consists of bonded curled fibres placed at random in a cell. The bonds show a stick-slip fracture behaviour. Results concerning the influence of network density, fibre orientation and ductility of bonds on the stress–strain behaviour of a network are given, and an example of fracture localization is provided.
