Aging and Fracture of Human Cortical Bone and Tooth Dentin
Mineralized tissues, such as bone and tooth dentin, serve as structural materials in the human body and, as such, have evolved to resist fracture. In assessing their quantitative fracture resistance or toughness, it is important to distinguish between intrinsic toughening mechanisms, which function ahead of the crack tip, such as plasticity in metals, and extrinsic mechanisms, which function pr...
متن کاملMixed-mode fracture of human cortical bone.
Although the mode I (tensile opening) fracture toughness has been the focus of most fracture mechanics studies of human cortical bone, bones in vivo are invariably loaded multiaxially. Consequently, an understanding of mixed-mode fracture is necessary to determine whether a mode I fracture toughness test provides the appropriate information to accurately quantify fracture risk. In this study, w...
متن کاملCortical Bone Fracture
The structural integrity of ‘‘hard’’ mineralized tissues such as bone is of great importance, especially because bone is the primary structural component of the body, serving as a protective load-bearing skeletal framework. As a structural material, bone is unique when compared with other engineering materials because of its wellknown capacity for self-repair and adaptation to changes in mechan...

متن کاملFatigue of mineralized tissues: cortical bone and dentin.
Gaining a mechanistic understanding of the mechanical properties of mineralized tissues, such as dentin and cortical bone, is important from the perspective of developing a framework for predicting and preventing failure of teeth and whole bones, particularly with regard to understanding the effects of microstructural modifications from factors such as aging, disease, or medical treatments. Acc...
