Fracture Mechanics of Osteonal Cortical Bone

Research Category: 
ITS and FEA of skeletons

Application of fiber-matrix composite fracture mechanics methods to predict strength, fracture process in osteonal cortical bone. It has been long hypothesized that cortical bone behaves like a fiber-matrix composite material without any verification. The purpose of this study is to verify applicability of current fracture mechanics techniques for fiber-matrix composites to cortical bone, to quantify contributions of various microstructural components to fracture properties of cortical bone.
