Advances in the fracture mechanics of cortical bone
TLDR
Values have been established for the critical stress intensity factor (Kc) and the critical strain energy release rate (Gc), which depend on the orientation of the cortical bone, as well as on bone density, the velocity of crack propagation and specimen geometry.About:

Bone structure and formation: A new perspective
Matthew J. Olszta,Xingguo Cheng,Xingguo Cheng,Sang Soo Jee,Rajendra Kumar,Rajendra Kumar,Yi-Yeoun Kim,Michael J. Kaufman,Elliot P. Douglas,Laurie B. Gower +9 more
TL;DR: In this article, the authors proposed a new model to explain how intrafibrillar mineralization of collagen can be achieved during bone formation, which is based on the concept of intra-fibrilar mineralisation, which refers to the fact that growth of the mineral phase is somehow directed by the collagen matrix.

On the Mechanistic Origins of Toughness in Bone
TL;DR: In this article, the authors review the structure and properties of bone, focusing on mechanical deformation and fracture behavior from the perspective of the multidimensional hierarchical nature of its structure and derive its resistance to fracture with a multitude of deformation mechanisms at many size scales ranging from the nanoscale structure of protein molecules to the macroscopic physiological scale.

Mechanistic aspects of fracture and R-curve behavior in human cortical bone
TL;DR: In an attempt to measure slower growth rates, it was found that the behavior switched to a regime dominated by time-dependent crack blunting, similar to that reported for dentin, which permitted subcritical crack growth to readily take place at higher stress intensities.

Fracture of Bone
TL;DR: In this article, the authors measured the energy required to propagate a crack and observed the mechanism of fracture by microscopically observing the fracture mechanism of bone at low strain rates, showing that bone displays very high resistance to crack propagation comparable even to some metallic materials.

Fracture mechanics of bone—The effects of density, specimen thickness and crack velocity on longitudinal fracture
J.C. Behiri,William Bonfield +1 more
TL;DR: The fracture mechanics parameters of critical stress intensity factor and critical strain energy release rate for longitudinal fracture of bovine tibia cortical bone were determined by the compact tension method and demonstrated that, for a given bone density, Kc and Gc depended on the loading rate, and resultant crack velocity.

TL;DR: Fatigue tests to failure of compact adult bovine bone specimens were conducted at five stress amplitudes and four temperature levels which span the physiologic range of bone temperature in the human foot.

TL;DR: The microscopic yield stress (the stress to produce a plastic strain of 2×10−6 in./in.) and the variation of plastic strain with applied stress have been established for bone as mentioned in this paper.
