Comparison of reduced model predictions for divertor detachment onset and reattachment timescales in ASDEX Upgrade and JET experiments
Building on prior analysis of ASDEX Upgrade (AUG) experiments (Henderson et al 2023 Nucl. Fusion 63 086024), this study compares simple analytical formula predictions for divertor detachment onset and reattachment timescales in JET experiments. Detachment ...
Iop Publishing Ltd2024Experimental Investigation of Instability-Free Welded Moment Connections With Simplified Weld Details
Dimitrios Lignos, Andronikos Skiadopoulos
In capacity designed steel moment resisting frames, inelastic deformations are mostly concentrated in the steel beams and the column fixed ends of the first story. This design concept limits the participation of the column web’s panel zone in the energy di ...
2023Laser powder bed fusion of Fe-based shape memory alloys for novel structural metamaterials and "smart" structures
Laser powder bed fusion (LPBF) is a powder-based additive manufacturing (AM) technique, which shows great potential in the production of complex-shaped parts with unprecedented design freedom. In addition, it allows for an active manipulation of the micros ...
EPFL2023Divertor detachment and reattachment with mixed impurity seeding on ASDEX Upgrade
Using newly developed spectroscopic models to measure the divertor concentration of Ne and Ar, it is shown that the experimental detachment threshold on ASDEX Upgrade with Ar-only and mixtures of Ar+N or Ne+N scales as expected in comparison with an analyt ...
IOP Publishing Ltd2023Full-scale testing of European steel beams with reduced beam section under reversed cyclic loading
Dimitrios Lignos, Hiroyuki Inamasu
Steel beams with reduced beam section (RBS) are often used as part of prequalified connections in seismic regions. However, RBS connections are not as common in Europe. Reasons relate to easiness in fabrication, which requires on-site welding, and the seis ...
Springer Nature2022Realistic Modelling of Dynamics at Nanostructured Interfaces Relevant to Heterogeneous Catalysis
The focus of this short review is directed towards investigations of the dynamics of nanostructured metallic heterogeneous catalysts and the evolution of interfaces during reaction-namely, the metal-gas, metal-liquid, and metal-support interfaces. Indeed, ...
MDPI2022Generation of elastic geodesic gridshells with anisotropic cross sections
Corentin Jean Dominique Fivet, Nicolas Robin Montagne, Olivier Baverel
Geodesic gridshells are shell structures made of continuous elements following geodesic lines. Their properties ease the use of beams with anisotropic cross-sections by avoiding bending about their strong axis. However, such bending may arise when flatteni ...
2021Development of Lamb wave resonators in thin film X-cut lithium niobate
Microelectromechanical systems (MEMS) is among the most revolutionary technologies of 21st century, with the applications ranging from industrial systems to consumer electronics. Using MEMS in battery-powered wireless devices has long been seen as the evol ...
EPFL2021Experimental investigation of the cyclic properties of welds in mild structural steels
Structural steels have long been used in construction applications. Their mechanical properties and behavior under seismic loading or under fatigue design are of considerable interest for researchers and engineers. Although extensive studies have been cond ...

Harshita Raj, Ankit Kumar, Abhijit Sen, Rohit Kumar
Short bursts (similar to 1 ms) of gas, injecting similar to 10(17)-10(18) molecules of hydrogen and/or deuterium, lead to the observation of cold pulse propagation phenomenon in hydrogen plasmas of the ADITYA-U tokamak. After every injection, a sharp incre ...
