Abstract
The analysis of the bone fracture behaviour is fundamental for prevention, diagnosis and treatmentof traumas. In the present paper, an experimental analysis of the fracture behaviour of a bovine femoral corticalbone is carried out, where specimens are extracted from a diaphysis. Fracture toughness is computed byemploying a two-parameter fracture model originally proposed for concrete. In order to take into account thepossibility of crack deflection (kinked crack) due to osteons orientation, a modified version of such a model ishere discussed. The fracture toughness results are then compared with those reported in the literature, relatedto a femur of an 18-month-old bovine.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
