摘要
文章利用有限元软件对圆形薄板的屈曲问题进行了计算,在不同的计算单元模式下,计算结果差异很大.选取的单元形式合适时,计算结果与理论分析一致.结果表明,常用的板和壳单元对于薄板的屈曲问题有着一定的局限性.在进行有限元软件计算时,选择合适的单元非常重要.
The finite element software is used to solve the buckling problem of circular thin plate. Various results arise under the different element modes. The numerical results will match the theoretical ones when the proper element mode is selected. It is concluded that the plate and shell mode plays an important role in solving the buckling problems.
