磁场和载荷联合作用下板的稳定性分析

Stability Analysis of Slabs Under Combined Force of Magntic Field and Load

用解析方法研究外加磁场和载荷联合作用下板的弯曲稳定性问题,考虑磁场的有限尺寸效应,给出了问题的一般解法。以四边简支矩形板和悬臂板梁(Beam-plate)为例给出了数值结果。通过和已有的数值结果、实验结果相比较,表明了本文分析方法的正确性,并且具有良好的计算精度。

Bending strength stability of slabs under applied magnetic field and machenical load was studied using analytic method. The limited dimension effect was taken into account, and a general solution was given.As examples, rectangular slab simply supported at its four edges and can-tilever slab were analysed. Comparing the numerical results with test results indicated that the analytic method is correct and has favorable accuracy.
