Annual Review of Physical Chemistry, 2007
Theoretical calculations on undefected nanoscale materials predict impressive mechanical properties. In this review we summarize the status of experimental efforts to directly measure the fracture strengths of inorganic and carbon nanotubes and discuss possible explanations for the deviations between the predicted and observed values.

The Mechanism of Skull Fracture
Radiology, 1950Deformation patterns of the skull due to blows of low velocity, as well as the mechanism of production of linear skull fracture, have been previously described (1–5). When the dry skull is coated inside and out with “stresscoat” brittle lacquer, and then subjected to a blow, the lacquer cracks in the areas of greatest tensile deformation.

Fracture Mechanics of Fracture Mirrors
Journal of the American Ceramic Society, 1979Stress‐intensity‐factor calculations were used to account for variations in the shapes of fracture mirrors caused by surfaces and by nonuniform stress fields (flexure). The validity of the stress‐intensity criterion for crack branching was confirmed. The stress‐intensity factor at crack branching, K B

Mechanisms of Fracture Healing
Hospital Practice, 1991Bone is remarkable in that...it regenerates itself. In fact, it is the only tissue...except the liver with that regenerative capacity....The stages of healing in fracture callus recapitulate the spatial zones seen in the growth plate of a child.

Fracture mechanisms and fracture mechanics at ultrasonic frequencies
Fatigue & Fracture of Engineering Materials & Structures, 1999Performing fatigue tests at ultrasonic frequencies, e.g. 20 000 Hz, allows one to perform experiments beyond 109and 1010cycles within half a day or a week, respectively. The testing technique has led to the construction of fatigue machines of high technical standard.

Mechanism of the Laterobasal Fractures
Acta Oto-Laryngologica, 1968Thirty temporal bones of cadaver's skulls after fatal head injuries have been investigated. During explorations it has been ascertained that the transverse fractures of the pyramid involving the middle ear walls do not damage the ossicular chain, whereas the longitudinal fractures of the pyramid involving the middle ear walls are as a rule associated ...

Strength of Materials, 1989
Quantum fracture mechanics (QFM) is proposed by the author as a purely theoretical alternative of the generally accepted experimental-theoretical approach to fracture physics. The main concepts of theory and formulation of several main problems are examined.

Journal of Biomechanical Engineering, 1993
This paper reviews the progress that has been made in applying the principles of fracture mechanics to the topic of fracture of long bones. Prediction of loading conditions which result in the propagation of fractures in bones has been of interest to the field of trauma biomechanics and orthopedics for over one hundred years. Independent verifications,

Fracture and Fracture Mechanics
1981Griffith was the first to offer an explanation for brittle fracture. He postulated that in a brittle material, cracks propagate when the released strain energy is just sufficient to provide the surface energy for the creation of new surfaces. That is elastic strain energy per unit volume = σ2/2E, where σ = stress applied perpendicular to the crack, E =
