Abstract
Bone tissue is a composite material composed of hydroxyapatite (HAp) and collagen. As HAp particles in bone tissue are crystal structure, X-ray diffraction method can be used to measure the lattice strain of HAp. This work shows the relationship between lattice strain of HAp crystals and macroscopic strain of bone tissue. The strip specimens of30×6×0.8mm in size were cut from cortical bone in a shaft of bovine femur. The long axis of the specimen was aligned with the bone axial and tangential direction. A tensile device was developed to apply tensile load to the specimen during the X-ray irradiation. Macroscopic strain was measured by a strain-gage glued on the surface of the specimen. Lattice strain of HAp in the specimen was measured by the X-ray diffraction method. As a result, the relationship between applied macroscopic strain and lattice strain was found to depend on Young's modulus of bone tissue.
