The coupling current loss in rectangular superconducting cables is strictly dependent on their aspect ratio, which has an impact on the area linked by the field variation and consequently on the currents induced between strands. The relation between the ac ...
Probabilistic model of coating fragmentation under uniaxial tensile loading is developed. Analytical expressions of the crack spacing evolution are obtained for small-strain and large-strain fragmentation regimes. The model is applied for coating and inter ...
Cabled conductors based on Nb3Sn technology with operating current in the range of 20 kA and above are mainly restricted to fusion magnets and high field facilities. The experience of last decade has dramatically shown that, opposite to the NbTi conductors ...
In the last few years, the critical current densities of long commercially available REBa2Cu3O7-x (RE-123, where RE represents Y or a rare earth element) coated conductors have reached values of 250 A/cm-width at 77K and zero applied field. Even higher val ...
This paper focuses on the experimental determination of the electrical resistance (R) of commercial high temperature superconductor (HTS) coated conductors (CCs) at currents well above the critical current. The major novelty of this work rests on the uniqu ...
The strain softening behavior of a particle-containing copper alloy and the associated microstructure changes were investigated as a function of strain rate (epsilon) over dot and analyzed by modeling. It is shown that, increasing strain rate (epsilon) ove ...
The ring strain energies of carbomeric-cycloalkanes (molecules with one or more acetylene spacer units placed into carbon single bonds) are assessed using a series of isodesmic, homodesmotic, and hyperhomodesmotic chemical equations. Isodesmic bond separat ...
We have examined the yielding and fracture behavior of Zr57.4Cu16.4Ni8.2Ta8Al10 metallic-glass-matrix composites with a small volume fraction (similar to 4 pct) of ductile crystalline particles under quasi-static uniaxial tension and compression and dynami ...
By making use of a novel diastereotopicity probe, namely C(CF3)(2)OH, it has been possible to measure by very low temperature F-19 NMR spectroscopy the elusive aryl aryl rotation barriers of biphenyls bearing an OH or F group in one rill position. The expe ...
This thesis reports on the successful use of low-energy metal ion implantation to fabricate compliant electrodes for miniaturized dielectric elastomer actuators (DEAs, also known as artificial muscles). DEAs are elastomeric actuators capable of large defor ...
