Deformation of the Cooling Vessel's Shell

open access: yesTehnički Glasnik
This paper will present the procedure for calculating the internal volume obtained by deforming the outer shell of the cooling vessel. A nonlinear finite element analysis was conducted using the Ansys software.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

open access: yesAdvanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Density waves in the outer disk of spiral galaxies

open access: yes, 2010
Several spiral galaxies display a prominent coherent spiral structure in their gaseous outer disk. Here we argue that these observed coherent patterns can be naturally interpreted as the manifestation of the mechanism that excites grand-design spiral ...

Experimental and Numerical Modal Analysis of Composite Sandwich Structures Using Surfboards as Model Systems

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents an experimental and numerical modal investigation of composite sandwich structures using surfboards as model systems. By comparing different core materials and reinforcement strategies, the study demonstrates how local stiffeners influence vibrational response and introduce characteristic modal features, highlighting modal ...

English or Englishes? Outer and Expanding Circle Teachers’ Awareness of and Attitudes towards their Own Variants of English in ESL/EFL Teaching Contexts

open access: yes, 2018
One of the challenging issues that has gained much attention, and has in fact sparked much debate, within the emergence and acquisition of World Englishes, is the Native- Non-native accent, especially its relationship with teachers’ and learners ...

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

open access: yesAdvanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Circle structure and orderly hydrocarbon accumulation of whole petroleum system in a continental fault basin: A case study of Kong-2 Member in Cangdong Sag, Bohai Bay Basin, China

open access: yesPetroleum Exploration and Development
Guided by the fundamental principles of the whole petroleum system, the control of tectonism, sedimentation, and diagenesis on hydrocarbon accumulation in a fault basin is studied using the data of petroleum geology and exploration of the second member ...

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

open access: yesAdvanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

The status of non-standard forms in the Outer and Expanding Circles

open access: yes, 2010
Over the last few decades, Outer Circle varieties have gained respect among linguists, as witnessed by the “gradual shift from exonormative to endonormative attitudes” (Bruthiaux 2003: 160).
