A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Numerical study of the characteristics of linear shear flow past two square cylinders in tandem arrangement

Shui kexue jinzhan, 2018
The convective outflow boundary condition is used in the multistep characteristic-based operator-splitting(MCBOS) finite element method. A numerical model for linear shear flow past square cylinders in tandem arrangement is established.

Magnetic point vortex and parasupersymmetry

Physics Letters B, 1993
Abstract We develop a formalism for point vortex interaction in parasupersymmetry. It is shown that vortices are compatible with parasupersymmetry and there are zero range interactions in some low angular momentum states.

Vortex Laser at Exceptional Point

, 2016
The optical vortices carrying orbital angular momentum (OAM) are commonly generated by modulating the available conventional light beam. This article shows that a micro-laser operates at the exceptional point (EP) of the non-Hermitian quantum system can directly emit vortex laser with well-defined OAM at will.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Evolution of Hydrodynamic Parameters of an Ellipsoidal Vortex in a Baroclinic Background Flow

Russian Journal of Earth Sciences
This study examines the behavior of a circular ellipsoidal ocean vortex in an external baroclinic flow with vertical shear. It is established that the vortex lifetime under fixed initial parameter conditions strongly depends on the external shear ...

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.
