The Failure Criteria for Soils
Canadian Geotechnical Journal, 1974Analysis of experimental results using extended Tresca and extended Von Mises criteria show substantial difference between experimental and predicted values particularly when the intermediate principal stress approaches the major principal stress. Modified forms of these criteria have been suggested and examined for their validity.

Failure Criteria for FRP Laminates
Journal of Composite Materials, 2005A new set of six phenomenological failure criteria for fiber-reinforced polymer laminates denoted LaRC03 is described. These criteria can predict matrix and fiber failure accurately, without the curve-fitting parameters. For matrix failure under transverse compression, the angle of the fracture plane is solved by maximizing the Mohr-Coulomb effective ...

Arboricultural Journal, 1993
Summary A field study of hollow tree trunks has shown an upper limit of hollowness of 70 per cent of the radius prior to failure, i.e. with a ratio of solid wall thickness t over a radius R > 0.3 tree breakage will be avoided. Wind throw has also been studied as an alternative failure mode.

In the usual tests to determine strength or lifetime under tension, bending or compression loading a uniaxial stress state is present. In components very often multi-axial stresses occur. Also under uniaxial external loading multiaxial stresses are possible, for instance in notched components.

Interface Fracture: Failure Criteria
Journal of Applied Mechanics, 2020Abstract Failure criteria for a crack between two dissimilar materials are presented. Test data from three different material pairs are considered. The first two consist of an interface crack between glass and epoxy and two dissimilar ceramic clays.

ACR Appropriateness Criteria® on Renal Failure
The American Journal of Medicine, 2014Imaging plays a role in the management of patients with acute kidney injury or chronic kidney disease. However, clinical circumstances strongly impact the appropriateness of imaging use. In patients with newly detected renal dysfunction, ultrasonography can assess for reversible causes, assess renal size and echogenicity, and thus, establish the ...

Research Criteria for male erectile failure
Journal of Sex & Marital Therapy, 1981Although the spectrum of psychosexual disorders is rather broad, there is a specific subgroup of sexual function disorders which has recently received wide attention due to the increased treatment success reported with the use of primarily behavioral means.

Failure Mechanisms and Criteria
2004Failure of structural elements can be defined in a different manner. As in the case of buckling, a structural element may be considered failure though the material is still intact, but there are excessive deformations. In Chap. 6 failure will be considered to be the loss of integrity of the composite material itself.
