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

Metals, 2023 Weld defects such as porosity, inclusion, burn-through, and lack of penetration are difficult to detect and control effectively in an orthotropic steel deck (OSD), which will be a fatigue crack initiation site and lead to several fatigue cracking.

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.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Fatigue crack growth of cast austenitic stainless steels
工程科学学报, 2015 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
