Abstract: Cancellous bone in the vertebral bodies of human cervical spine was tested under compression and tension at strain rate of 10-3/s. Experimental methodology (such as cutting method, gripping method, precondition procedure, and strain measurement) was established for such porous bio-material. The average properties and stress-strain curves were obtained, which showed higher modulus/failure stress and lower ultimate strain in compression than in tension. Discussion on density measurement was described. The fresh bone density, apparent bone density, bone tissue density as well as porosity ratio are obtained for the cancellous bone in human cervical spine. Elastic modulus, strength and failure strain were fitted against bone density. Empirical nonlinear constitutive equations against bone density were constructed for both compression and tension, and showed good predictions for their nonlinearity till ultimate strain. The obtained mechanical properties as well as corresponding analysis shall be a meaningful contribution to the database of cancellous bone in human cervical spine. © The Society for Experimental Mechanics, Inc. 2013.
