MODELLING OF THE FEMORAL FRACTURE UNDER DYNAMIC LOADING

Bone is a living material with a complex hierarchical structure that gives it remarkable mechanical properties. The bone undergoes constant mechanical and physiological stress, so its quality and its resistance to fracture evolve constantly over time through the process of bone remodelling. Bone quality is not only defined by bone mineral density but also by mechanical properties as well as micro architecture. The aim of this work is to model the fracture of the femur bone under a quasi-static and dynamic solicitation in order to create a digital model simulating the fractures of this element due to an accident. This modelling will contribute to improve the design of the means of transport to bring a better security to the passages. To achieve this goal, the modelling by the finite element method is performed to study the mechanical behaviour of bone structure and predict femur fractures.
