Effect of different environmental conditions on surface crack growth in aluminum alloys [PDF]
Fracture and Structural Integrity, 2017 . Fatigue surface crack growth is studied through experiments and computations for aluminum alloys D16T and B95AT (analogue of 2024 and 7075 aluminum). Subjects for studies are cylindrical hollow specimens with external semi-elliptical surface crack. The

Relation Between Scatter in Crack Growth Rate and Small Crack Growth Law.
Journal of the Society of Materials Science, Japan, 1994 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.

Modeling of creep-fatigue interaction effects on crack growth at elevated temperatures
MATEC Web of Conferences, 2018 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.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
