STRAIN DEPENDENCE OF DYNAMIC YOUNG MODULUS FOR HUMAN SINGLE OSTEONS

The strain dependence of Young's modulus for human single osteons was investigated by subjecting the sample to cyclic tension/compression at frequencies near 10**3 Hz by means of a small acoustic speaker. On average, deviations from linear dependence occurred at 2% strain and plasticity followed at 4% strain. The modulus itself averaged at 12-14 GN/m**2 and is comparable to values obtained both by J. Black (1972) and by W. R. Smith Jr. and D. A. Keiper (1965) for samples containing many osteons at frequencies of 350 and 500-3500 Hz respectively.
