Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]

, 2013
This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Measurement and simulation of strain fields around crack tips under mixed-mode fatigue loading [PDF]

Fracture and Structural Integrity, 2015
For various configurations examined in a series of fatigue experiments on thin-walled tubes under tension and torsion, the experimental results – crack path, crack growth life, near crack tip deformations, and crack closure – are measured and compared to

Full‐field characterization of a fatigue crack: Crack closure revisited [PDF]

Fatigue & Fracture of Engineering Materials & Structures, 2018
AbstractThe full‐field of a fatigue crack, ahead and behind the crack tip, has been examined in this work using Digital Image Correlation. We measured, in situ, the surface crack opening displacements at selected locations behind the crack tip and the evolution of the near‐tip displacements and strains ahead of the crack tip, during loading and ...

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.

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

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

Fatigue Crack Growth Rate of the Long Term Operated Puddle Iron from the Eiffel Bridge

Metals, 2019
The paper summarises an experimental study on the fatigue crack propagation and cracks paths in ancient steel—19th-century puddle iron from the Eiffel bridge. The tests were performed with the load R-ratio equal to 0.05 and 0.5.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
