TL;DR: It is demonstrated how the physics of ice formation can be used to develop sophisticated porous and layered-hybrid materials, including artificial bone, ceramic-metal composites, and porous scaffolds for osseous tissue regeneration with strengths up to four times higher than those of materials currently used for implantation.

TL;DR: It was found that fracture in human cortical bone is consistent with strain-controlled failure, and the influence of microstructure can be described in terms of several toughening mechanisms, such as uncracked-ligament bridging.

TL;DR: In this paper, the effect of DR on the low-cycle fatigue (LCF) and high cycle fatigue (HCF) behavior of a Ti-6Al-4V alloy is examined, with particular emphasis on the thermal and mechanical stability of the residual stress states and the near-surface microstructures.

TL;DR: In addition to a reduction in trabecular bone volume, GC treatment reduced bone mineral and elastic modulus of bone adjacent to osteocytes that was not observed in control mice nor estrogen‐deficient mice, which could amplify the bone fragility in this metabolic bone disease.

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.
