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 ...

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

Study of Stress and Deformation of High Concrete-Face Rockfill Dam on Steep Slope in Narrow Valley

Renmin Zhujiang, 2022
At present,in the finite-element stress and strain calculation of rockfill dams,fixed support is mostly adopted to simulate the connection between the rockfill at the bank slope and the slope.As for a concrete-face rockfill dam (CFRD) in the steep slope ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Global Sliding Mode Fault-Tolerant Control for Nonholonomic Wheeled Robots: Ensuring Prescribed Performance in the Presence of Faults and Slippage

IEEE Access
This paper proposes a global integral sliding mode control (GISMC) scheme integrated with an improved disturbance observer (IDO) for robust trajectory tracking of nonholonomic wheeled mobile robots under uncertainties, disturbances, wheel slippage, and ...

Optimum Winding Tension and Nip-load into Wound Webs for Protecting Wrinkles and Slippage

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
This paper describes the novel optimization method of wind-up tension to prevent wound roll defects, mainly star defect (wrinkling) and telescoping (slippage), based on the optimum design technique.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

Understanding Slippage in Automated Market Makers: A Unified Deviation Framework and Survey

Blockchains
As a major cost in decentralized asset swapping, slippage is commonly measured as the relative deviation between realized and expected outcomes. However, existing studies adopt different benchmarks, leading to ambiguity in terminology and the positioning
