Estimation of bone material properties using an inverse finite element method
نویسندگان
چکیده
Burst fractures are common fractures resulting from impact loading and can have severe consequences such as neurological deficits [1]. The biomechanical process which leads to burst fracture is still debated. Finite element models (FEM) could further our knowledge on burst fracture mechanism. A precise evaluation of the mechanical properties of bone tissues is a critical issue when creating these models [2]. The aim of this study was to evaluate the mechanical properties of bone components of the vertebral body. An inverse finite element strategy was used to estimate the properties of cortical and trabecular bone. These mechanical properties have been evaluated at two velocities in order to investigate the influence of the displacement rate.

Nanoindentation involves probing a hard diamond tip into a material, where the load and the displacement experienced by the tip is recorded continuously. This load-displacement data is a direct function of material's innate stress-strain behavior. Thus, theoretically it is possible to extract mechanical properties of a material through nanoindentation. However, due to various nonlinearities ass...
