Mechanical Properties and Bone Density of Bone Samples from Horses

Abstract

Mechanical properties and bone density (photon absorptiometry method) of bone samples from horses were studied. The dynamic stiffness and tan δ were measured by a viscoelastic spectrometer. The three-point bending test was performed with an Instron-type universal testing machine. A bone densitometer (Norland Instruments) was used for the density measurement. The results are as follows :(1) Three point bending test showed that deformation averaged 5.23 mm, and the fractured load, 22.4 KN. (2) There was a positive correlation between dynamic stiffness and bone density. (3) There was a negative correlation between tan δ and fractured load. (4) There was a positive correlation between Sr content and fractured load. (5) There was a positive correlation between the contents of Ca and P and Vickers hardness number.
