Science and Engineering of Short Fibre-Reinforced Polymer Composites, 2019
: The crack resistance of composites is characterised. Composite materials show extended damage zones in front of the crack tip comparable to plastic zones of homogeneous materials. The energy dissipation processes within these damage zones are qualitatively and quantitatively described.

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.

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 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.

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, KB, for flint glass was determined to be 2.55 MN m−3/2.

Inverse analyses in fracture mechanics [PDF]
International Journal of Fracture, 2006 The present purpose is a survey of some engineering-oriented research results which may be representative of the main issues in the title subject. Some recent or current developments are pointed out in the growing area of fracture mechanics centered on the calibration of cohesive fracture models for quasi-brittle materials, by approaches which combine ...
