Stresses in a bulk high-temperature superconductor are numerically evaluated during the magnetization process by field cooling. Shielding current distributions are obtained through a macroscopic numerical simulation with the Maxwell equations and the critical state model. The stress distributions are obtained through numerical analysis with the finite-difference method. Two numerical codes are combined in the iterative calculation. Peak values of the maximum hoop, radial and shear stresses are obtained under different conditions during the magnetization.
