Multiscale modeling of bone fracture using cohesive finite elements

Bone is a hierarc hical material that exhibit fracture mechanisms at multiple scales and will benefit from amultiscale eval uation approach for better fracture risk assessment. This study developed acohesive finiteelement modeling approach that simulated bone fracture at micro- and macroscale. Simulation results showed that the microscale fracture toughen- ing was most effective when the cement line had lower strength than the surrounding bone reducing the propensity to fracture at the macroscale. These results demonstrate the importance of cement line strength in controlling the fracture toughening mechanisms and the effect of microscale properties in the whole bone fracture risk assessment.
