Abstract

Experimentally based isotropic tensile and compressive strain yield criteria for cancellous bone are shown to imply tensile and compressive stress yield criteria, respectively. In particular, it is deduced that the directional variation of uniaxial yield stress is proportional to the one of Young's modulus. The obtained tensile and compressive stress yield criteria, in turn, imply information about the total stress yield criterion for cancellous bone.
