Dynamic Properties of the Shoulder Complex Bones

This paper reports on a characterization of stress-strain response of the humerus, clavicle and scapula through impact studies followed by property estimation. For the humerus, the modulus obtained for quasi-static tests varies between 0.4 to 18 GPa while the modulus obtained from the drop height of 0.5m varies from 0.7 to 40.5 GPa, that obtained from a drop height of 1m varies from 0.8 to 40.95 GPa and that from the 1.5m drop tests varies from 1.8 to 53 GPa. The increase in modulus with strain rate is consistent with earlier studies including McElahney.
