The study focus on biomechanical annulus fibrosus behaviour. On one hand, cyclic tensile tests are performed on annulus samples and bring out a non-linear behaviour with an important hysteresis on each cycle. On the other hand, digital image correlation allows to obtain surfacic strain fields in both anisotropic planes. Finally, a poro-elastic model in large strain is used to understand these observations.
