Investigation on the Crack Initiation of V-Shaped Notch Tip in Precision Cropping
Advances in Materials Science and Engineering, 2014 The crack initiation of V-shaped notch tip has a very important influence on the cross-section quality and the cropping time for every segment of metal bar in course of low stress precision cropping.

Risk Estimation for LCF Crack Initiation [PDF]
Volume 7A: Structures and Dynamics, 2013 An accurate risk assessment for fatigue damage is of vital importance for the design and service of today’s turbomachinery components. We present an approach for quantifying the probability of crack initiation due to surface driven low-cycle fatigue (LCF).

Quasi-static crack propagation by Griffith's criterion [PDF]
, 2008 We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith's criterion in a suitable form

A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]
, 2010 It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.
