弹性地基板的等参有限元法计算

Plates on an elastic foundation calculated by isoparametric element methods

提出了弹性半空间地基板的四节点和八节点等参元计算方法。该方法适用于弹性地基上不同形状的薄板或厚板的计算。算例表明，本文方法适应性强、精度较高，用较少的单元就能获得较好的结果。

The 4 nodes and 8 nodes isoparametric element methods are proposed for the plates on the elastic half space. The methods can be used for various thin or thick plates with different shapes. The examples have shown that the presented method can be used widely. They have higher accuracy,and good results can be obtained with a few elements.
