摘要
本文利用Wilson非协调三维元与16节点相对自由度壳元对复合材料管道三通进行丁有限元分析,成功克服了主支管交界处由于材料与结构不连续给分析带来的困难。计斡程序的可靠性已得到苦干算例验证。
In this paper, stress and strength analysis was made hy 3-D F. E. M fiber reinforced plastics (FRP)tees. The use of wilson' sincompatible element and 16-noded 3-D element with relative degrees of freedom is convenient to deal with the problem of intersection of two FRP pipes with different principal dircctions of the material. The reliability of the program has been verified in this paper.
