Radial and Hoop Compressive Stresses in a Long Cylindrical Superconductor With Viscous Flux Flow

摘要：

The radial and hoop stresses induced by flux pinning in a type-II bulk superconductor shaped as an infinitely long circular cylinder are discussed during an applied magnetic field increases after zero-field cooling. The magnetic response of the bulk superconductor to the applied magnetic field is described by solving the Bean model and viscous flux flow equation simultaneously. The calculations show that the radial and hoop stresses are compressive and influenced by the applied magnetic fields and velocities of viscous flux flow.
