Analytical solution on dosage of self-healing capsules in materials with two-dimensional multi-shaped crack patterns

open access: yesScience and Engineering of Composite Materials, 2018
This article presents a numerical method for determining the dosage of pre-embedded capsules in self-healing materials with complex crack patterns. The crack distribution on the surface of materials is simplified into a two-dimensional (2D) multi-shaped ...

Key aspects in 3D fatigue crack closure numerical modelling [PDF]

open access: yes, 2018
Since long time, fatigue crack closure has been studied by means of finite element models. Initially by bi-dimensional models and recently, due to the higher computational capabilities, the use of three-dimensional models has been extended, providing a

Propagation of surface initiated rolling contact fatigue cracks in bearing Steel [PDF]

open access: yes, 2016
Surface initiated rolling contact fatigue, leading to a surface failure known as pitting, is a life limiting failure mode in many modern machine elements, particularly rolling element bearings.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

AMLCD glass mirror constant and crack flaw size in non-crack LCD panels

open access: yesJournal of Information Display, 2016
Portable models based on the latest liquid crystal displays (LCDs) have been useful in various areas. Many developers have pursued thinner hardware as well as the advanced performance of portable models. Therefore, as the panel glass continuously becomes

Fatigue crack growth in a particulate TiB2 reinforced powder metallurgy iron-based composite

open access: yes, 2003
Fatigue crack growth behavior has been examined in a particulate titanium diboride (TiB2)–reinforced iron-based composite that had been produced via a mechanical alloying process.

Crackling noise in three-point bending of heterogeneous materials [PDF]

open access: yes, 2011
We study the crackling noise emerging during single crack propagation in a specimen under three-point bending conditions. Computer simulations are carried out in the framework of a discrete element model where the specimen is discretized in terms of ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Research on J integral of Crack Tip on Intersecting Line of Fracturing Pump Head

open access: yesShiyou jixie, 2018
To address the primary failure modes of the fracturing pump head, a finite element model with different angular crack size is established. The J integral of the crack front and the plastic zone size of the crack tip are calculated.
