Threshold crack growth behavior of shear and tensile cracks
International Journal of Fatigue, 2012Abstract Crack-face interference-free mode I and mode II crack-growth data was combined with smooth axial ( λ = e xy / e xx = 0) and torsional ( λ = ∞) endurance limit data to develop unified crack growth models that incorporate both shear and tensile cracking.

Crack growth and closure behavior of short fatigue cracks
Engineering Fracture Mechanics, 1994Abstract Crack growth and closure behavior of short cracks are investigated for various stress ratios, using in-plane bending specimens of 2024-T351 aluminum alloy. Artificially prepared two-dimensional, short through-thickness cracks are used.

Post buckling behavior of transverse cracked columns
Computers & Structures, 1984Abstract Post buckling behavior of a column with a transverse surface crack on the one side is studied, considering the local flexibility because of the crack. This flexibility, also called compliance, is known to be related to the stress intensity factor.

Cyclic Fatigue–Crack Propagation Behavior in Silicon Carbide: Long‐ and Small‐Crack Behavior
Journal of the American Ceramic Society, 2001Cyclic fatigue properties of high‐toughness SiC with additives of Al 2 O 3 and Y 2 O 3 were examined, with a focus on differences between long‐ (>3 mm) and small‐crack ...

Cracking and Compaction Behavior of Sandstone
Proceedings of SPE/ISRM Rock Mechanics in Petroleum Engineering, 1998Abstract Compression and extension tests with measurement of permeability and elastic wave velocity were made on two different sandstones. Distinctly different cracking and compaction behavior were observed in the two types of test. Conclusions are drawn for the choice of wellbore orientation and allowable pressures.

Copping crack: The travel behavior of crack users
Justice Quarterly, 1995Considerable attention has been directed to the incidence and distribution of crack in urban areas. In response to public concern about the presence of crack in residential neighborhoods, law enforcement agencies have implemented various law enforcement strategies aimed at reducing or eradicating drugs from urban environments. These strategies, however,

Crack resistance behavior of polyvinylchloride
Journal of Applied Polymer Science, 1997The effects of specimen dimension (thickness, width) and specimen configuration (SENB, CT), as well as test conditions (crosshead speed, temperature), over a range of crosshead speeds from 0.01 to 100 mm/min and temperatures from −40 to 60°C, on the crack growth resistance behavior were investigated in a commercial amorphous thermoplastic ...

Creep-fatigue crack propagation behavior in a surface cracked plate
Nuclear Engineering and Design, 1993Abstract A series of experiments were performed in order to clarify the surface crack growth behavior under creep-fatigue condition. Type 304 stainless steel was tested at 550°C and 650°C. Specimens were plates with a surface notch. Loading patterns were axial fatigue, bending fatigue, axial creep-fatigue and bending creep-fatigue.

Behavior of Small Fatigue Cracks
1996Abstract This article defines different types of small cracks and identifies the different factors that influence small-crack behavior. Appropriate analysis techniques, including both rigorous scientific and practical engineering treatments, are briefly described.

We have re-evaluated short crack growth behavior using concepts developed recently, and we show that these concepts provide a unified framework that can explain both short and long crack growth behavior without resorting to the crack closure effect. We consider that the behavior of long cracks, including the effects of load ratio, R, is fundamental. We
