Fracture Mechanics

In this second edition, which is the result of numerous revisions, updates and additions, the authors cover the basic concepts of fracture mechanics for both the linear elastic and elastic-plastic regimes. The fracture mechanics parameters K, G, J and CTOD are treated in a basic manner along with the test methods to determine critical values.

The Mechanism of Skull Fracture

Radiology, 1950
Deformation 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.

Nanoscale Fracture Mechanics

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.

Fracture Mechanics of Fracture Mirrors

Journal of the American Ceramic Society, 1979
Stress‐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

Fracture mechanisms and fracture mechanics at ultrasonic frequencies

Fatigue & Fracture of Engineering Materials & Structures, 1999
Performing 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.

Mechanisms of Fracture Healing

Hospital Practice, 1991
Bone 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.

Mechanism of the Laterobasal Fractures

Acta Oto-Laryngologica, 1968
Thirty 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 ...

Quantum Fracture Mechanics

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.
