High-Speed and Low-Load Twin-Roll Casting of Al–5%Mg Strip

open access: yesMetals, 2022
A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and a roll load greater than 2 kN/mm. A vertical-type high-speed twin-roll caster can cast aluminum alloy strips at a speed higher than 10 m/min and a roll load smaller ...

Application of the Reciprocity Theorem to Scattering of Surface Waves by a Surface Crack in Viscoelastic Material

open access: yesApplied Sciences, 2022
In this paper, the scattered surface waves created by a surface crack in a homogeneous, isotropic, viscoelastic half space within a plane strain condition was studied.

Elastic-plastic analysis of the crack surface vicinity under a pair of anti-plane forces applied at an arbitrary point on the crack surface

open access: yesAIP Advances, 2018
An elastic-plastic analysis of the mode III crack surface vicinity was performed in an infinitely wide elastic-perfectly plastic plate, in which a pair of anti-plane forces applied at an arbitrary point on the crack surface.

Fast crack propagation by surface diffusion [PDF]

open access: yesPhysical Review E, 2003
We present a continuum theory which describes the fast growth of a crack by surface diffusion. This mechanism overcomes the usual cusp singularity by a self-consistent selection of the crack tip radius. It predicts the saturation of the steady state crack velocity appreciably below the Rayleigh speed and tip blunting.

The analysis of bearing capacity of main pipeline in presence of corrosion defects [PDF]

open access: yesОмский научный вестник, 2019
A mathematical model is presented that allows modeling fatigue defects of corrosion origin on main pipelines. A method for assessing the crack resistance of the main pipeline wall with a corrosion defect is proposed.

A safety assessment approach to pressure vessels based on machine learning

open access: yesFrontiers in Materials, 2022
The safety assessment of a pressure vessel with a surface crack is an important part of the safety assessment of engineering equipment. However, the existing methods are mostly based on the assumption of plane specimens and the K criterion applicable to ...

Perturbatıon Solution for a Cracked Euler-Bernoulli Beam

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
The natural frequencies and mode shapes of an Euler-Bernoulli beam with a rectangular cross- section, which has a surface crack, is investigated. The crack is modeled as a change (sudden or gradual) in the cross-section of the beam, and a modified ...

INFLUENCE OF SURFACE CRACKS ON THE STABILITY OF CRACKED SOIL SLOPE

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2022
The slope stability is a major concern to geotechnical engineers. Traditional methods of slope stability analysis have potentially ignored the influence of surface cracks. It is also known that seasonal rainfall and seepage through crack are closely related with slope failure.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
