Abstract

Human anulus fibrosus (AF) of the intervertebral disk exhibits nonlinear and anisotropic behavior in tension. This paper investigates both anisotropic and nonlinear behaviors of the AF in the confined compression testing configuration under conditions of finite deformation. The finite deformation formulation of the biphasic theory is used to described the experimental stress-relaxation behavior of AF under conditions of large deformation. In this formulation, the equilibrium elastic behavior is described by two material parameters: the aggregate modulus at zero strain (H_Ao) and the nonlinear stiffening coefficient (β).
