A note on fracture criteria for interface fracture

International Journal of Fracture, 2000
Several criteria for interface fracture are examined and compared to test results obtained from glass/epoxy specimens. These include two energy release rate criteria, a critical hoop stress criterion and a critical shear stress criterion. In addition, approximate plastic zone size and shape within the epoxy are determined for these tests.

Criteria for Failure and Fracture

2020
Structural members may have geometric features (including holes, notches, and corners) that result in localized regions of high stress called stress concentrations. The ratio C of the maximum stress resulting from a stress concentration to a defined nominal stress is called the stress concentration factor.

The impact of subtrochanteric fracture criteria on hip fracture classification

Osteoporosis International, 2011
Hospital diagnosis codes are useful for assessing hip fracture rates in large populations. However, these codes do not reliably differentiate hip fractures that occur in the subtrochanteric region. Identification of subtrochanteric fractures requires review of radiographic images to distinguish these fractures from the more commonly occurring ...

Rock Fracture Criteria

2010
When stresses in the Earth’s crust exceed the crustal strength, the rock fractures and fails (Brace 1964; Hoek 1968; Obert 1972). A fracture criterion describes the conditions for which failure occurs in a material. In principle, one distinguishes between phenomenological and mechanistic failure theories.
