In-situ SEM study of slip-controlled short-crack growth in single-crystal nickel superalloy

open access: yesMaterials Science & Engineering: A, 2019
Initiation and growth of short cracks in a nickel-based single crystal were studied by carrying out in-situ fatigue experiments within a scanning electron microscope (SEM). Specimens with two different crystallographic orientations, i.e., [001] and [111],

The Effects of Breathing Behaviour on Crack Growth of a Vibrating Beam

open access: yesShock and Vibration, 2018
The effects of breathing behaviour on the dynamic response and crack growth are studied through a cracked cantilever beam. The main goal is to reveal the coupling mechanism of dynamic response and crack growth by employing a plain single-degree-of ...

Crack Linkup by Stable Crack Growth

open access: yesComputer Modeling in Engineering & Sciences, 2000
Experimentally determined Tε* and CTOA resistance curves were used to simulate numerically, stable crack growth and the ensuing crack linkup in 0.8 mm thick 2024-T3 aluminum tension specimen with multiple site damage (MSD) subjected to monotonically/cyclically increasing loading. The Tε* integral correctly predicted the crack growth and

Experimental and simulation study on Ⅰ-Ⅱ mixed-mode fatigue crack growth of TC4-DT welded joint

open access: yesJournal of Aeronautical Materials, 2020
The crack growth in the structure shows the complex Ⅰ-Ⅱ mixed-mode under the combined tensile and shear fatigue loading. It is of great significance to understand its growth law for evaluating the fatigue life of structures accurately.

Assessment of crack growth development in main pipeline on the basis of elastoplastic model [PDF]

open access: yesОмский научный вестник, 2019
A method for predicting the growth of surface cracks in the wall of the main pipeline under action of operational loads is proposed. The elastoplastic model of surface crack growth under biaxial loading is described on the example of steel 20.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS 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.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS 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

Study on crack evolutional behavior of rocks in triaxial compression based on colony growth dynamics model

open access: yesScientific Reports, 2022
The crack propagation behavior of rock during compression involves complex mechanisms. Describing the growth behavior of a large number of cracks with conventional mechanical models is a major challenge.
