| dc.description.abstract | Bovine cortical bone is a complex hierarchical material with a strong anisotropic mechanical behavior. Its deformation and fracture under shear loading are not well understood, especially in relation to the bone microstructure. Therefore, this brought the aim of this study to determine the shear fracture load of cortical bone with respect to its microstructure orientation, to examine the crack-propagation of cortical bone under shear with respect to its microstructure orientation and to characterize the strain field in cortical bone under shear. This study investigated the shear deformation and fracture behavior of bovine cortical bone using Iosipescu shear tests. Specimens were prepared at different angles with respect to the long axis of the bone, and the shear strength and fracture pattern were measured. The results showed that bovine cortical bone has a higher shear strength when sheared parallel to the long axis of the bone. The fracture pattern was also affected by the orientation of the bone, with cracks generally following the direction of the long axes of the osteons. Digital image correlation (DIC) analysis revealed that shear strain concentration bands were aligned with the long axis of the bone. These results suggest that the shear deformation and fracture behavior of bovine cortical bone is strongly influenced by its microstructure. This study provides new insights into the mechanical behavior of cortical bone under shear loading. The results could be used to improve the design of artificial bone implants and to develop new treatments for bone fractures. | |
