Abstract
The nonideal inelastic buckling behavior of single trabeculae from the subchondral region of the human medial tibial plateau was investigated. Wet specimens exhibited ductile buckling, whereas dry specimens buckled in a brittle manner. Extrapolation to ideal slenderness ratios showed Young's modulus to be 1.65 × 10⁶ psi in the wet state and 2.05 × 10⁶ psi in the dry state, reasonably similar to cortical bone.
