The buckling analyses of type-II superconducting strip under applied perpendicular magnetic field and/or distributed uniform mechanical load are investigated in this paper. Based on the Bean critical state model, the electromagnetic body force is firstly given. Then, based on the classical plate theory and two-point initial value method, the critical buckling states of the superconducting strip with different boundary conditions are analyzed. Numerical results show the effects of both the thickness and boundary conditions of superconducting strip on the corresponding critical buckling loads. The present work should be helpful to the research and application of superconducting thin strips.

II型超导薄带在垂直磁场和平行分布均匀机械载荷作用下的磁弹性屈曲特性

本文研究了II型超导带材在垂直磁场和/或分布均匀机械载荷作用下的屈曲分析。基于Bean临界状态模型，首先给出了电磁体力。然后，基于经典的板理论和两点初值法，分析了不同边界条件下超导带材的临界屈曲状态。数值结果表明，超导带的厚度和边界条件对相应的临界屈曲载荷的影响。目前的工作将有助于超导薄带的研究和应用。
