摘要
本文以三维块体有限元及薄壳有限元为基础,将新型接触面单元应用于块体和壳体之间,该单元不仅解决了六个自由度的壳体与三个自由度的多介质体相互过渡问题,更重要的是可以模拟土体与壳体之间的相对滑移等现象,计算土体与壳体间的相对位移、切向力、法向正应力。
The contact face element is applied in the analysis of the interaction of cylinder shell and multi medium. This method is based on the block and shell finite element method. The problem of different degree of freedom between shell and multi medium is solved by means of the interim element contact face element, moreover, the sliding between shell and soil body can be imitated and the relative displacement, friction force and normal stress can also be calculated.
