| Research Abstract |
When mechanical and/or electromagnetic stress exceeds a critical value in superconducting composite tape, damage of superconducting phase takes place, resulting in reduction of superconducting property. Accordingly, for evaluation of property and design with high reliability, it is needed to describe quantitatively the influence of stress state on fracture behavior and superconducting property. In the present work, non-destructive estimation method of stress response of the constituents by usi ng X-ray anomalous scattering and simulation method of stress-dependence of superconducting property in stressed coated- and filamentary- composite conductors were developed.
