How Mn and Ti Promote Metal Dusting in NiCu Alloys

Materials and Corrosion, EarlyView.
Cu/MnO catalysis mechanisms of CO lead to C uptake in NiCu alloys and a fairly uniform layered metal dusting attack. Mn effectively eliminates the catalytic inhibition benefits of Cu in NiCu alloys. Rather Cu is detrimental if Mn is present as it promotes MnO catalysis.

Image‐Based Flaw Identification Using Convolutional Neural Network

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Flaw detection in structures is crucial for ensuring structural integrity and safety across various engineering applications. Traditional nondestructive evaluation (NDE) techniques often face challenges in accurately identifying and characterizing flaws, particularly when dealing with complex geometries and strain fields.

Numerical Modeling of the Recession and Closure of Planar Hydraulic Fractures: Contact‐Based Versus Asymptotic‐Informed Schemes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

The effect of compliance assistance on pollution discharges and violations of environmental regulations

Journal of Policy Analysis and Management, EarlyView.
Abstract Researchers and policymakers assert competing behavioral models of polluters. One model portrays polluters as best approximated by the perfectly informed, rational actor from economics textbooks. Another model portrays polluters, particularly small and medium facilities, as imperfectly informed, cognitively bounded, pro‐social actors.

Testing 3D Printed Carbon Fiber Durability for Next‐Gen Fusion Reactors via Proton Irradiation

Polymer Composites, EarlyView.
Schematic of proton irradiation effects on carbon fiber samples evaluated via nanoindentation and Raman spectroscopy. ABSTRACT Carbon fiber‐reinforced composites are promising candidates for plasma‐facing components (PFCs) in next‐generation fusion reactors due to their high strength‐to‐weight ratio, thermal stability, and radiation resistance. However,

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation

Polymer Composites, EarlyView.
Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.
