“…The current study by Ina et al [6] on the fatigue properties of cortical bone and radiation sterilization dose builds on previous work highlighting the importance of improving our understanding of the relationship between radiation sterilization and mechanical properties [1, 2, 5, 7, 9-12], as well as the chemical composition of cortical bone [4]. Ina et al [6] reported a dose-dependent decrease in fatigue life and a sixfold decrease in the mean cycles to failure of cortical bone between 17.5 kGy and 25 kGy.…”

“…Enamel: Chemical and structural gradients inhibit the fatigue crack initiation and propagation; damages can be repaired by the hydroxyapatite nanorod remineralization ( 10 , 39 ). Cortical bone: Sacrificial bond rupture and collagen fibril sliding impede the crack initiation; microcrack, ligament bridges, and weak interface induce the crack deflection and slows the crack propagation; remodeling substitutes old or damaged bone with new bone tissue ( 9 , 40 ). Metal: Twin boundaries (TB) and grain boundaries (GB) suppress dislocation activities; nano inclusions retard microcrack propagation ( 41 ).…”

The hinge of bivalve shells can sustain hundreds of thousands of repeating opening-and-closing valve motions throughout their lifetime. We studied the hierarchical design of the mineralized tissue in the hinge of the bivalve Cristaria plicata , which endows the tissue with deformability and fatigue resistance and consequently underlies the repeating motion capability. This folding fan–shaped tissue consists of radially aligned, brittle aragonite nanowires embedded in a resilient matrix and can translate external radial loads to circumferential deformation. The hard-soft complex microstructure can suppress stress concentration within the tissue. Coherent nanotwin boundaries along the longitudinal direction of the nanowires increase their resistance to bending fracture. The unusual biomineral, which exploits the inherent properties of each component through multiscale structural design, provides insights into the evolution of antifatigue structural materials.

“…First, the longitudinal and transverse tissue-level elastic moduli of the corresponding rat femoral cortical bone samples have been measured by previous nanoindentation test, as shown in Table 4 [ 22 ]. The poisson's ratio was set to 0.3 [ 1 , 14 ]. Additionally, the ratio of critical tensile to compressive failure strain of the cortical bone material was set to 0.6 according to the literature [ 35 , 36 ].…”

“…Cortical bone bears most of the external loads, and once damage occurs in the cortical bone structure, cracks will propagate under different loads and eventually lead to fracture [ 1 , 2 ]. The inevitable degeneration in the mechanical properties of cortical bone with age will further increase the incidence of fracture [ 3 ].…”

Background Running with the appropriate intensity may produce a positive influence on the mechanical properties of cortical bone structure. However, few studies have discussed the effects of different running intensities on the mechanical properties at different levels, especially at the micro-level, because the micromechanical parameters are difficult to measure experimentally. Methods An approach that combines finite element analysis and experimental data was proposed to predict a micromechanical parameter in the rat femoral cortical bone structure, namely, the micro-level failure strain. Based on the previous three-point bending experimental information, fracture simulations were performed on the femur finite element models to predict their failure process under the same bending load, and the micro-level failure strains in tension and compression of these models were back-calculated by fitting the experimental load–displacement curves. Then, the effects of different running intensities on the micro-level failure strain of rat femoral cortical bone structure were investigated. Results The micro-level failure strains of the cortical bone structures expressed statistical variations under different running intensities, which indicated that different mechanical stimuli of running had significant influences on the micromechanical properties. The greatest failure strain occurred in the cortical bone structure under low-intensity running, and the lowest failure strain occurred in the structure under high-intensity running. Conclusions Moderate and low-intensity running were effective in enhancing the micromechanical properties, whereas high-intensity running led to the weakening of the micromechanical properties of cortical bone. Based on these, the changing trends in the micromechanical properties were exhibited, and the effects of different running intensities on the fracture performance of rat cortical bone structures could be discussed in combination with the known mechanical parameters at the macro- and nano-levels, which provided the theoretical basis for reducing fracture incidence through running exercise.
