| Summary: | capture variations in the microstructure, no single parameter compact bone from other species may show similar trends. completely predicts the differences in moduli. Although the composite material. The method of ultrasound is appropriate for estimating moduli provided that the frequency is greater than the characteristic dimensions that define the Haversian compact bone as homogeneous solid. This study Haversian compact bone behaves as a mildly transversely isotropic material that can be modeled as a fiber reinforced material properties exhibit gradual increases for small may differ from the actual mechanically measured values, the mechanically measured moduli. Although the ultrasonic values microstructure. The ultrasonic moduli are analogous to the moduli and the shear moduli show greater dependence on ash observed that mild changes in the microstructure can predict of the anisotropic moduli in all principal directions. When positive changes in ash weight and gradual decreases for relatively low at 5 or lower such that the wavelength is results of this study are limited to equine specimens, small changes in porosity. Longitudinal elastic moduli shows test, one can calculate absolute mechanical properties for the greatest negative dependence on porosity. The transverse ultrasonic moduli accurately predict the relative magnitudes used in combination with an additional mechanical tensile variations in the mechanical properties. All the tested weight percent. As one must use several parameters to |
