Dynamic Response of Vertebral Elements.

Abstract

Creep response and relaxation data, obtained from shear, torsion, and compressive stress tests of the intervertebral disc, are used to develop an analytical model. A series chain of four Kelvin units was found to provide an excellent representation of the viscoelastic properties of the material; this model led to the development of two-element model with a time dependent viscous coefficient. The two element model characterizes the mechanical properties of the intervertebral disc in a concise representation suitable for computer utilization. (Author)
