A bone has a hierarchical structure as shown in Fig. 1 [1]. Macroscopic bone properties are dependent on the microstructure and properties of structural elements. The bone is a composite material that consists of hydroxyapatite particles in a matrix of collagen fiber. Borsato et al. [2] measured the strain of hydroxyapatite by X-ray diffraction and obtained clear evidence of the stress concentr...
