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. To estimate a stress in bone tissue from the lattice strain measured, it has to be found that a relationship between the lattice strain and macroscopic strain of bone tissue. This work presents a method to constitute an anisotropic bone model composed of HAp and collagen matrix. To make an optimal bone model, anisotropic elastic modulus was evaluated by comparing with actual elastic modulus of cortical bone in a shaft of bovine femur. The relationship between the strain of HAp phase and macroscopic strain of bone tissue was obtained from the optimal FEM model.
