Mechanical properties of tibial bone at compressive strain rates of 50–200/s are obtained through a Split Hopkinson pressure bar. Cylindrical specimens of 12–15 mm diameter and 2–5 mm thickness were prepared. The Young's moduli are calculated from linear portion of stress–strain curves. For both cortical and cancellous part of the bones, the Young's modulus was found to increase with the increasing strain rates. Also for both cancellous and cortical bones, the Young's modulus increases consistently with increase in densities.
