Cortical Bone Model with a Microcrack under Tensile Loading

The fracture mechanics of cortical bone has received much attention in biomedical engineering. It is a fundamental question how the material constants and geometric parameters affect behavior bone. In this work, plane problem for with microcrack located interstitial tissue under tensile loading was considered. Using solution continuously distributed edge dislocations as Green's functions, formulated singular integral equations Cauchy kernels. numerical results suggest that soft osteon promotes propagation, while stiff repels it, but interaction effect between limited near osteon. This study not only sheds light on also offers inspiration design bioinspired materials
