采用嵌入不连续方法求解夹层问题

A Solution for the Problem of Interlayer by Using Embedded Discontinuous Method

采用嵌入不连续方法对整体结构的夹层问题进行分析 ,将与整体结构不同材料的夹层嵌入到常规有限单元 ,并在嵌入不连续单元的位移场中引进非协调位移模式。通过一个含有弹性夹层的算例说明了将嵌入不连续方法运用于求解夹层的可行性及合理性 。

The embedded discontinuous method is used for analyzing the interlayer in the massive structure. The interlayer distinguished from integral structure by its material is embedded to regular element and an incompatible displacement mode is added in displacement field of embedded discontinuous element. The feasibility and rationality to solve interlayer using the embedded discontinuous methods are explained through a numerical example containing elastic interlayer. Thus, a new idea to overcome the difficulties of mesh refinement in the complex foundation containing soft interlayer is proposed.
