In this study, an attempt was made to directly measure a complete set of Poisson's ratios and tensile moduli required for a description of the anulus fibrosus (AF) as an orthotropic material. Using a new method for surface strain measurement, it was demonstrated that the surface strain is nearly uniform under uniaxial tension for all orientations and all strain magnitudes. While the determined material coefficients form a complete set, the measured values did not correspond with the predicted relations between material coefficients for an orthotropic linear material.
