Abstract

An initiation fracture toughness methodology for cortical bone under shear (mode II) loading is presented. Using our compact shear specimen (1) with modified boundary conditions and the compliance method, the mode II critical strain energy release rate (GIIc) of human bone was measured. GIIc of male and female human bone aged 57 to 89 years ranged between 137 to 1848 N/m with an average value of 951 N/m (s.d. = 521 N/m). The shear fracture toughness of human bone was found to decrease with age (R2 = 0.37). Results were consistent with other fibrous composite materials.
