Some experimental observations of crack-tip mechanics with displacement data [PDF]
Fracture and Structural Integrity, 2015 In the past two decades, crack-tip mechanics has been increasingly studied with full-field techniques. Within these techniques, Digital Image Correlation (DIC) has been most widely used due to its many advantages, to extract important crack-tip ...

Crack-size and crack-orientation distributions of brittle materials.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1989 In this report, we derived a new theory by combining the previously obtained statistical theory fracture location with the multiaxial distribution function. Using this theory, we analysed not only 3 crack-size ditribution function but also the crack-orientation distribution. Both distribution function are considerably affected by the fracture criteria.

Fatigue Life Assessment and Reliability Analysis of Cope-Hole Details in Steel Bridges
The Baltic Journal of Road and Bridge Engineering, 2020 Cope-hole details are widely applied to steel bridges. However, the safety of steel bridges is influenced by the fatigue performance of welded details.

Fractal scaling and crack-size effects on creep crack growth
Strength, Fracture and Complexity, 2020 Scaling effects on the creep crack growth behaviour are investigated by analyzing the results of compact tension (CT) tests on different-sized notched steel specimens appearing in the literature. Creep crack growth rate data are correlated to the elastic stress-intensity factor in terms of a Paris-type law, da∕dt = C0Kq, where C0 turns out to be a ...

VIBROTHERMOGRAPHIC CRACK HEATING: A FUNCTION OF VIBRATION AND CRACK SIZE
AIP Conference Proceedings, 2009 Vibrothermography is an inspection technique that detects cracks by observing vibration induced crack heating. Frictional crack heating in a vibrating specimen is directly linked to the resonant vibrational stress on the crack. In simple geometries we can measure the vibrational mode structure and intuit the dynamic vibrational stress field on the ...

On a kinked crack model to describe the influence of material microstructure on fatigue crack growth [PDF]
Fracture and Structural Integrity, 2013 Threshold condition and rate of fatigue crack growth in both short and long crack regime appear to be significantly affected by the degree of crack deflection.
