Abstract

Because mechanical spine properties having multiple degrees of freedom (DOF) are generally difficult to measure, we developed a parallel 6-axis material tester with hybrid position/force control. We give examples of 6-axis testing and results of material tests using polyurethane rubber and animal spines.
