Multivariate Seismic Fragility Analysis of a Nuclear Power Plant Containment Based on Generalized Conditional Spectra

Yuanzineng kexue jishu, 2023
Seismic hazard analysis and seismic fragility analysis are import parts of seismic risk analysis of the nuclear power plant, and the site-specific spectra generation and selection of ground motion records are the key connecting steps between seismic ...

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

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

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Variabilities of ground motion in 2023 M w 7.8 Pazarcık earthquake in Turkey and 2008 M w 7.9 Wenchuan earthquake in China

Scientific Reports
Both the 2023 M w 7.8 Pazarcık earthquake (strike-slip fault) in Turkey, and the 2008 M w 7.9 Wenchuan earthquake (reverse-slip fault) in China occurred on the Eurasian seismic belt, with comparable moment magnitudes.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Intensity measures considering directivity of near-fault ground motion and optimal selection for bridges -- case study in the Wushi earthquake

Geomatics, Natural Hazards & Risk
This paper proposes omnidirectional ground motion intensity measures (OGMIMs) to intuitively characterize two-dimensional ground motions, using the magnitude 7.1 Wushi earthquake as a case study to investigate the directional characteristics and spatial ...
