Kinetics of crack growth in zirconium alloys (I): Temperature dependence of the crack growth rate

Journal of Applied Physics, 2009
Delayed hydride cracking (DHC) tests were conducted on a cold-worked Zr–2.5Nb tube with hydrogen at different test temperatures ranging from 100 to 350 °C. Striation spacing corresponding to a critical hydride length increased with temperature, demonstrating that hydride cracking resistance is enhanced with temperature.

Kinetics of crack growth in zirconium alloys (II): Stress dependence of the crack growth rate

Journal of Applied Physics, 2010
Delayed hydride cracking tests were conducted on a cold-worked Zr-2.5Nb tube with hydrogen at different test temperatures ranging from 160 to 280 °C in the load increasing mode where an applied KI was increased step-wise by 0.5 MPa m1/2 from 4.5 MPa m1/2.

Rate transitions in the fatigue crack growth of elastomers

Journal of Applied Polymer Science, 2008
AbstractIt has been observed previously that cracks in elastomers under repeated strain initially grow rapidly from sharp cuts, but as the cracks proceed, the rate decreases to a steady value. This work examines these transitions from a sharp crack tip, introduced by a razor blade into a pure shear test piece, for a range of elastomers.

The Analysis of Fatigue Crack Growth Rate Data

1979
The analytical variables associated with the characterization of fatigue crack growth rate performance are discussed and the influence of these variables on predicted cyclic life is illustrated. It is shown that the analytical techniques chosen to process laboratory test results and to develop upper-bound design information can have a significant ...

Fatigue Crack Growth Rate Recommended in BS7910 and an Unique Crack Growth Rate Curve Under Different Load Ratios

Volume 1: Codes and Standards, 2007
It is still difficult to select the proper constants of crack growth rate corresponding to the loading condition for R-ratio has significant effect on crack growth rate. An unique crack growth rate equation, taking equivalent stress intensity factor range (ESIFR) as the driving force, has been examined for steels and as welded joints.

A strain-rate dependent model for crack growth

1992
Classical continuum mechanics approach for determining the stress and/or strain distribution is solids in based on the assumption of a constitutive equation which is assumed to depend on the material while the interaction of material with local stress and/or strain is neglected. The form of the constitutive equation is preassumed and is taken to be the
