Fracture of geometric bone models. Multiscale simulation issues

Abstract

Fracturing of osseous models is a field that allows to obtain advances in computer-assisted medical simulations, as well as to prototype fragile objects as is the case of bones. This field of study includes the use of physical features of bones. Not all fracturing methods are valid with osseous models, due to the importance of considering the hierarchical structure of the bones. In this work, we focus on the study of bone fractures at the macroscale level and on obtaining fractures with a realistic appearance. Therefore, a tool has been developed that allows the fracture of osseous models, obtained through a 3D scanning process, by the use of patterns and physics. The different approaches for the fracturing of osseous models are also shown, and discussed the need to obtain more information about the fracturing process.
