In this study, bone strength evaluation method using a response of hammering test was considered. In the method, transfer function of the bone is measured, and the response level which is stable at lower frequency of first resonance is obtained. On the other side, a relationship function between the response level and bending stiffness of the bone using theoretical beam vibration model is calculated. After then, the bending stiffness of the bone through the relationship function and the obtained response level is estimated. For the verification of the method, bending stiffness of some test pieces, which bending stiffness were already known, were estimated by using this method. As results, the obtained bending stiffness was very close to the actual value. From these consideration and experiments, the method is considered to be a suitable bone strength evaluation method.
