Grass can be modelled satisfactorily as an orientated fibrous composite. The fibres account for 90 to 95 % of the longitudinal stiffness. The grass leaf shows little or no notch sensitivity together with a specific work-of-fracture of approximately 30 Jm−2. This probably affects the way in which animals gather grass when they feed on it.
