In tokamaks, a strong and stable toroidal magnetic field is essential for plasma confinement. Among the available materials for toroidal field coil, REBCO is a promising candidate due to its excellent stability margin and high critical magnetic field. However, the design and analysis of toroidal field coils, which consist of multiple components such as REBCO-coated conductors, solder,...

Structural issues in high-temperature superconducting (HTS) magnets under high magnetic fields have garnered significant attention in recent years. While much of the research has focused on the electromagnetic forces induced by operational and screening currents during magnet operation, the mechanical behavior of HTS magnets during fabrication and cooling stages remains underexplored.

When designing magnets with strong magnetic fields, it is imperative to consider the mechanical stress induced by the Lorentz force. However, conventional stress-strain calculation methodologies, or force balance equations that utilize the BJR formula, often neglect the frictional force between superconductor tapes. This motivated our previous study on the relationship between the frictional...

The REBCO coated conductor (CC) tapes used in high-field magnets are subjected to a variety of mechanical and thermal loads, including stress during the manufacturing process, Lorentz forces during operation, as well as repeated electromagnetic and thermal cycles. It is crucial for the magnet designers to know the fatigue properties of CC tapes to ascertain their service life under operating...

High-temperature superconducting (HTS) magnets, fabricated by winding HTS tapes, are widely utilized in various advanced applications. During operation, these HTS magnets and their wound HTS tapes are subjected to compressive loads caused by external factors such as winding tension, thermal contraction during cooling, and electromagnetic forces, leading to mechanical deformation. Previously,...

Reinforced BSCCO wire has been considered to have a small margin of strength on the compression side because the filaments has been introduced to compressive strain. However, due to the presence of a sheath and the difficulty of observation, there were no examples of actual fracture behavior in compression. In this paper, we report on in situ microscopic observations of BSCCO filaments exposed...

Age-hardened Cu-Zr sheets are used in resistive magnetic field application. In this work, we studied the fatigue properties of Cu-Zr and Cu sheets. Three categories of Cu-Zr sheets with different strength were investigated and compared. Our investigation showed that their fatigue life was related to their ultimate tensile strength (UTS). Materials with higher UTS demonstrated longer fatigue...
