    Abstract

    Standard test methods to evaluate the material properties of cortical bone do not exist. A test methodology that accounts for the anisotropy of cortical bone by subjecting the material to multiple modes of loading is proposed. The four test included are axial compression parallel to the longitudinal axis, tensile load perpendicular to the long axis (diametral compression), double lap shear, and three-point bend. These methods provide a means of documenting the biomechanical changes that may occur as a result of unique attributes inherent to a donor or the processes that the donor tissue is exposed. Several examples illustrate how these methodologies demonstrate the relationship between process and mechanical properties.
