Two-Dimensional Stress Distributions in Disk and Ring High-Tc Superconductors

Stresses in a bulk high-T c superconductor (HTS) are numerically evaluated when the bulk HTS is fully magnetized by field cooling. The stress distributions for disk and ring models are obtained through numerical analyses with the finite-difference method. Differences between one- and two-dimensional solutions are examined using the Bean model in terms of the maximum tension stress and shear stress.
