分析了矩形板形形状的硬型II超导体的磁通诱导的磁磁体。使用平面应变方法发现了磁弹性三维问题的精确解。所有应力和应变成分均以平板中的通量密度曲线表示，并申请任何关键状态型J C5 J C（B）。在一定长度上讨论的是为下降磁场出现的拉伸应力。提出了BEAN模型和指数模型的结果。 @S0163-1829〜99！08217-x＃
The flux-pinning-induced magnetostriction of hard type-II superconductors shaped as a rectangular slab is analyzed. An exact solution of the magnetoelastic three-dimensional problem is found using the plane strain approach. All stress and strain components are expressed in terms of the flux-density profile in the slab, and apply for any critical-state model j c5 j c(B). Discussed at some length is the tensile stress occurring for a descending magnetic field. Results for both the Bean model and the exponential model are presented. @S0163-1829 ~99!08217-X#
