The main goal of this article is to present a combined methodology (experimental and numerical) for femur fracture onset analysis. Experimental work includes the characterization of the mechanical properties and fracture testing on a bone simulant. The numerical work focuses on the development of a model whose material properties are provided by the characterization tests. The fracture location and the early stages of the crack propagation are modelled using the extended finite element method and the model is validated by fracture tests developed in the experimental work. It is shown that the accuracy of the numerical results strongly depends on a proper bone behaviour characterization.engjournal article0090-6964https://doi.org/10.1007/S10439-017-1877-628639173https://link.springer.com/article/10.1007/s10439-017-1877-6https://pubmed.ncbi.nlm.nih.gov/28639173/restricted access617Bone mechanical behaviourComposite boneFemur fractureFracture predictionNumerical modellingXFEMMedicinaCirugía32 Ciencias Médicas3213 Cirugía
