摘要
对Reissner-Mindlin板提出了一种非协调稳定化组合有限元格式.采用三种非协调元进行了数值计算.结果表明该方法可以克服locking现象,对网格畸变不敏感,若适当调整参数,就有高精度.
Non-conforming stabilized combined finite element method is presented to approximate the Reissner-Mindlin plate. Three finite element spaces are applied to the computation. Numerical results show that the method can avoid the locking phenomenon and is not sensitive to mesh distortion. If proper parameter is chosen, it shows high accuracy at coarse meshes.
