摘要
就弹性力学问题,我们给出了两种新的混合有限元格式,这两种格式都较现有的同阶格式[1,2]节省了自由度,而且论证方法也较简便.同时,该格式也适用于三维问题.
Elasticity problems are studied and two new formats of mixed finite element are proposed.The formats save on freedom-degrees and are simper and more convenient than those in [1-2]. Ob viously, they are also applicable to three-dimensional problems.
