N2 - A general, nonlinear, anisotropic finite element method using ABAQUS is developed to model the lumbar facet joint capsule. The method was validated using measured uniaxial, stiffness properties from the cat. Stress and strain were calculated by sequential procedures calls. Except for the lowest strain rate, there was no significant differences between uniaxial stress curves indicating that short time response of the facet capsule is largely invariant of strain rate within approximately two orders of magnitude. As expected, facet capsule was viscoelastic and demonstrated nonlinear stiffness.
