Relation Between Scatter in Crack Growth Rate and Small Crack Growth Law.
In order to investigate the scatter characteristic of growth rate for small cracks, rotating bending fatigue tests of smooth specimens were carried out using a normalized 0.21% carbon steel. Fifteen specimens were fatigued at each stress range, and the growth rate of major cracks was calculated from the smoothed growth curve for all the specimens.

A Modified Loading Method for Separating the Effect of Residual Stress on Fatigue Crack Growth Rate of Welded Joints [PDF]
A novel loading method is proposed to remove the effect of residual stress on measured fatigue crack growth rate in welded joint, using which the influence of empirical crack growth rate correlation equations on the results can be avoided.

Modeling of creep-fatigue interaction effects on crack growth at elevated temperatures
The well-known load frequency effect on creep-fatigue crack growth is explained by the interactions between fatigue and creep loading and is quantified using the concept of plasticity-induced crack closure.

Finite element analyses of fatigue crack growth under small scale yielding conditions modelled with a cyclic cohesive zone approach [PDF]
Mode I fatigue crack growth is modelled and investigated with a cohesive zone approach. A 2D finite element boundary layer model under plane strain and small scale yielding conditions is used to generate fatigue crack growth rate curves ...

ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

Fatigue crack growth of cast austenitic stainless steels
The influences of stress ratio, single overload and high-low loading sequence on the fatigue crack growth of Z3CN20-09M cast austenitic stainless steels were studied with compact tension specimens. When the stress intensity factor range is identical, the
