Thermomechanical Validation of an Additively Manufactured Test Chamber for Sustainable Aviation Fuel Atomization in Jet‐In‐Crossflow Conditions

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT This study aims to validate the structural and thermomechanical reliability of an additively manufactured test chamber specifically designed for the experimental investigation of sustainable aviation fuel (SAF) atomization under jet‐in‐crossflow (JICF) conditions representative of gas turbine afterburners. The proposed test chamber is designed

Fracture Assessment of DEMO Divertor Components Under Thermo‐Mechanical Loads

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT Nuclear fusion represents a promising pathway toward large‐scale, sustainable, and low‐impact energy production. However, the extreme operating conditions within fusion reactors, characterized by high temperatures, intense neutron irradiation, and severe mechanical and magnetic loads, place significant demands on the structural integrity of ...

Structural Optimization of 3D Braided Tungsten–Copper Composites via Active Learning and Finite Element Simulation

open access: yesMaterials Genome Engineering Advances, EarlyView.
An uncertainty‐aware FEM–GPR active learning framework efficiently explores the design space of 3D braided W–Cu composites, identifying architectures with higher yield strength and preserved electrical conductivity, whereas SHAP interpretation highlights yarn spacing in the braid plane as the key structural factor controlling composite performance ...

A Comparison of Classical Constitutive Models for High‐Entropy Alloy Behavior: Effects of Medium Strain Rates and Temperature on Plastic Flow

open access: yesMaterials Genome Engineering Advances, EarlyView.
Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...

Anisotropic Initial Damage and Its Effect on Tensile Response of Plain Concrete

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Damage is often described as isotropic, implying that a scalar value describes its initial state. However, the prior micro‐cracking pattern at points of an existing building, that is, the initial damage, may be oriented by a preload. The degradation of the Volume Element due to oriented preloads shall be described as anisotropic and ...

Population recovery of an endangered macaw enhances long‐distance seed dispersal via stomatochory

open access: yesOikos, EarlyView.
Seed dispersal by large, mobile vertebrates plays a key role in shaping plant spatial dynamics and community structure. However, how variation in animal population size influences the magnitude and spatial scale of seed dispersal remains poorly understood.

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

open access: yesPeople and Nature, EarlyView.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...
