Mechanical Competence and Bone Quality Develop During Skeletal Growth. [PDF]
Bone fracture risk is influenced by bone quality, which encompasses bone's composition as well as its multiscale organization and architecture. Aging and disease deteriorate bone quality, leading to reduced mechanical properties and higher fracture ...

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Delamination resistant composites by interleaving bio-based long-chain polyamide nanofibers through optimal control of fiber diameter and fiber morphology [PDF]
In this work an innovative electrospinning system is proposed that simultaneously has an adequate temperature resistance, a high increase in mode I (þ51%) and mode II (þ96%) delamination performance and can be commercially produced.

Role of Alcohol in the Fracture Resistance of Teeth [PDF]
Healthy dentin, the mineralized tissue that makes up the bulk of the tooth, is naturally hydrated in vivo; however, it is known that various chemical reagents, including acetone and ethanol, can induce dehydration and thereby affect its properties. Here, we sought to investigate this in light of the effect of alcohol on the mechanical properties of ...

Evaluation of the Effect of Furcation Perforation on the Fracture Resistance of Endodontically Treated Mandibular Molars [PDF]
Background: Root perforations are among the most common procedural complications during root canal treatment; these complications have a poor prognosis.

Small scale fracture behaviour of multilayer TiN/CrN systems: Assessment of bilayer thickness effects by means of ex-situ tests on FIB-milled micro-cantilevers [PDF]
TiN/CrN multilayered PVD coatings are known to exhibit outstanding micromechanical properties and wear resistance. On the other hand, information on their small scale fracture behaviour is rather scarce.

Fracture-resistant monolithic dental crowns [PDF]
To quantify the splitting resistance of monolithic zirconia, lithium disilicate and nanoparticle-composite dental crowns.Fracture experiments were conducted on anatomically-correct monolithic crown structures cemented to standard dental composite dies, by axial loading of a hard sphere placed between the cusps.
